Fallout: New Vegas bugs

General advice and notes
Bethesda's FNV support page offers many simple solutions to common problems.
 * Make sure your game is patched to the latest official patch. If your game is not up-to-date, do not report any bugs you may experience.
 * Save often and in different slots. Do not rely too much on autosave. A frequently overwritten autosave slot can become corrupted.
 * If you are playing on the PC, make sure your computer meets or exceeds the minimum system requirements. If any component of your computer falls below the minimum system requirements, do not report any bugs you may experience.
 * Installing the game can help greatly cut down load times and lessen glitches triggered by entering certain locations or interacting with certain NPCs. If you are experiencing game freezing and frame rate drops, loading screens that last 60 seconds and longer, or multiple crashes ensuing from the same action or location, installing the game can help with some of these issues. It may also help to clear your console cache (found under "memory > device options") which will then prompt you to re-download any patches issued on XBL when you next launch the game.

Mods

 * The Vault does not cover information concerning third-party mods for Fallout: New Vegas.
 * If you have any mods installed, do not report any bugs you may experience, even if it seems to you that your issue is not mod-related. Please visit the Bethesda mod forums for information.

Using the console
On the PC, many NPC, quest, and player-getting-stuck issues can be resolved through the use of console commands.

Crashing, freezing and other hardware- or software-related issues
Stuttering, crashing, freezing, and slow-down issues are often hardware- and/or software-related. Please visit the Bethesda Fallout: New Vegas hardware forums for information regarding these issues. In particular, read through the stickied threads at the top of the forum pages.

Game-play bugs

 * Boxes or jars of ammo primer or powder are useless and take up weight until dropped or stored in a container, and then picked up again, at which time the quantity of weightless ingredients is added to the inventory. This applies to most boxes and jars with a few exceptions, such as "Ammo Box, Micro-fusion Cells", which are correctly added as ammo immediately. In hardcore mode, this 'bug' is actually a benefit; a box of 250 x 5.56mm Surplus rounds weighs only 5 WP as opposed to 250 x 0.03 = 7.5 WP.(Confirmed)
 * Purchasing the strength implant does not increase strength when at level 7.
 * Jumping on the Sarsaparilla crates results in a loud crash, followed by your character abruptly taking serious damage. Process is repeatable.
 * Occasionally clothing and armor is not properly unequipped, resulting in being attacked for no reason by enemy factions. Example: If the NCR starts attacking for no reason, re-equip Legion armor and unequip it again. Make sure you receive the message that you are no longer dressed in Legion clothes.
 * Do not at any point attempt to sell any faction armor that is currently equipped as it will result in you receiving the notice that the armor has been removed and you are no longer dressed as the said faction. You will be unable to select "A" to accept the message, if you do hit "A" it will simply sell or buy the next item in the list. When this happens, if you press the start button and then resume, you are then able to get rid of the notification.
 * Sometimes weapons do not properly hot key when multiple items are being assigned.
 * Failing quests due to reputation problems may not reset upon restart. Ex: I received bad rep in Freeside because a companion killed a resident. When I restarted from auto-save, the game would not allow me to begin the mission with the Kings.
 * If you are using the Gatling laser and you switch weapons, the Gatling backpack may sometimes glitch onto your back. It cannot be removed even if you drop all your weapons and/or armor. There are two ways to fix this; reload to a previous save not affected by this phenomenon OR reset the game console (in case you auto-saved with the bugged backpack on).
 * Occasionally, when you try to engage in sex dialog with another character, the screen goes black for a moment before returning to normal. Money is subtracted but there is no blacked out sex scene. Fisto seems to work correctly, however.
 * Creatures (seemingly at random) will not die; instead, an alert will pop up informing the player that they are unconscious. They then proceed to regain consciousness, and cannot be truly killed no matter how many times one tries.  Reloading an earlier save will not fix this, and it can be a problem even with creatures killed prior to the bug -- I loaded up a game from 10 hours before this bug appeared, fast traveled to Goodsprings Source, and the geckos you kill with Sunny Smiles at the very beginning were all alive again.  I'm guessing that it's something to do with the update, since it appeared quite suddenly.
 * The "Sneak" skill has no difference in effect from 50 - 100. Only factors are the amount of light, running (pre-perk), stepping on some obstacles, and line of sight.
 * If "True Iron Sights" is disabled, many modded weapons when aimed will block the target reticule and obscure all view.
 * Sometimes your character will hold the gun above the screen if you're in first person. Switching from first person to third person and back will fix this bug; alternatively, you can access your Pip-Boy.
 * Often when pickpocketing the "pick" is not counted, does not count towards the challenge and achievement, and your karma will not be adjusted.
 * While using a melee weapon in VATS while standing on railway track, sometimes the player becomes stuck waste high in the terrain.
 * Be warned when executing the buy/sell Infinite Caps exploit, when you rack up a huge 'buy' price and complete the transaction, you may not be able to gain caps through selling loot. (Confirmed on Xbox 360)
 * Randomly, (Usually after combat or a big fall) your First-Person Camera will be from the point of view of your characters chest

Custom button-mapping bugs
Using custom control-mappings can cause problems when attempting to activate or use objects, fire weapons, reload, etc. This glitch was triggered for me after moving Frag Grenades from a container into my inventory. The game would then simply freeze and necessitate a hard reset upon bringing up the weapon-mapping legend or by selecting any direction on the D-Pad.

Fix: Unload all your equipment into a container. When you pick it all up again you can once again use the D-pad (Xbox 360).

Caravan bugs

 * When buying cards for your caravan deck, they will just sit in your inventory and you won't be able to add them to your deck.
 * Fixed on PC with patch 1.1.1 (Hopefully others when their patch goes through)
 * When discarding cards from your hand in your initial turn (before you place any cards down on the table,) the third card from the left in your hand seemingly changes randomly to another card in your deck. Once the animation for drawing a new card is completed however, the card returns to its initial value. For example: The three right most cards in my hand might be a 7, 9, and a Queen. Once you choose to discard the Queen for example, the 7 changes to another card in my deck, possibly a 9. Therefore, while the animation for discarding a card and drawing a new one is taking place the two rightmost cards will appear two nines. Once the animation is finished and the player is able to make another move, the nine will then change back to its actual value of 7.
 * Upon winning the player gets the amount of caps in the pot added to their cap total, though the in game message only reports adding half the pot. This is only when the player wins, if the NPC wins the caps are removed and added properly from both. (i.e. NPC bets 800, you call. If You win you get 1600 caps instead of 800, if NPC wins they only get 800.)

Pip-Boy bugs

 * The Pip-Boy screen may increase in brightness to a point where you can't see anything on the screen. (Saving and loading the new save can fix this on PS3 and xbox 360)(Turning on then off the pip boy light can fix this on PS3 & Xbox)
 * In some instances when the player turns on their Pip-Boy's light, the entire sky may glare up, regardless if day or night.(Confirmed)
 * In H&H Tool Company the dates on the journal entries hidden on the secret network drives do not match the dates of the same journal entries on the Pip-Boy (they are ten years earlier on the Pip-Boy).
 * When bringing the Pip-Boy screen up, the Pip-Boy moves partially off screen, occluding the view of the Pip-Boy screen. (Confirmed for X360)
 * Occasionally the damage threshold indicator (Ex: DT 10.0) in the top-right of the Pip-boy screen will disappear (Just the letters 'DT' and the value - all other parts of the screen are fine). Resetting the console, and reloading the save, seems to fix it.
 * Entering Pip-boy then Immediately alt-tabbing out of Fallout: New Vegas before the pip-boy opens. Then return to game, The menu will be up but you can still walk freely around, but you can not interact with anything or equip anything.
 * On the 'Stats' screen, certain stats are not accurately reflected. For example, I have consumed water hundreds of time so far, yet 'water consumed' reads as zero. Unsure if the bug is related only to the pip-boy display, or if the game is not properly tracking

NPC-specific bugs

 * For NPC-specific bugs, please see the respective NPC article page.
 * For bugs that apply to NPCs in general or to followers in general, please see the General NPC bugs section below.

Quest-specific bugs
For quest-specific bugs, please see the respective quest article page.


 * During The House Always Wins if the player character returns to the Lucky 38 and gives the Platinum chip to Mr. House before activating the securitron army at the fort, the quest becomes stuck. Mr. House will send the player to activate the bots but he doesn't return the chip to the player so that the player can actually enter the vault resulting in a broken quest. The only way around this is to activate the bots before turning in the chip to Mr. House.
 * The unnamed quest to find the food processor parts doesn't allow you to fix the processor even if you have all the parts, one more part is needed. You will need one extra Pot in your inventory, only one pot will be removed when fixing the food processor. It is unknown if PS3 is affected.
 * During the Debt Collector quest, if you choose to gather the caps from Lady Jane's cache in the cave, when you go to turn in the caps to Francine Garret, you will have to choose the option to LIE even though you've recovered all of the debts. This doesn't not seem to effect the quest completion, as Francine doesn't care where you got the caps as long as she got her caps back.
 * During I Could Make You Care Veronica will walk up to and talk to Elder McNamara to initiate a scripted sequence of dialog. If the player walks up to McNamara thus leading Veronica to engage the scripted dialog and then speak to a NPC (such as a brotherhood of steel knight standing guard at the doorway) right before the scripted sequence, it will bug the sequence and both McNamara and Veronica will stand idle. The player will not be able to engage McNamara or Veronica in dialog and the companion wheel is disabled when talking to Veronica. Console commands of disable then enable, kill then resurrect, will not restore McNamara or Veronica to their previous states. (McNamara can jump out of script even without Veronica. He then just stand in the hallway on 1st floor, telling player to wait for him to return to office.)
 * Return to Sender If you talk to Ranger Andy in Novac before you start this quest, Ranger Station Charlie gets wiped out so there is no way to bring the update to that Station. It will remain a quest objective until you return to Rayes where you can finish the quest. (EDIT: I did that, and it didn't show as an objective on PC - Jay of Gamerfill)
 * After the guard duty mission for the Van Graffs at Silver Rush, going back outside and stealing the Van Graff armor makes it a permanent item in your inventory that cannot be dropped as it is considered a "Quest Item". The only way to drop the Van Graff armor is to start the 3rd Side quest for the Van Graffs. Once you are arrive in the building with the Legion you are able to drop both sets (the set you stole and could not drop before, and the set they gave you for this quest) *Note: The only way to start the 3rd side quest for the Van Graffs is to (obviously) do the 2nd quest, but to complete the 2nd quest you must let them kill you're companion, Cass. You can also do the Brotherhood quest Tend to Your Business and kill the Van Graff, allowing the armor to be dropped as you fail the related quest for them.
 * During Guess Who I Saw Today, before letting Doctor Henry experiment on Lily Bowen, when you kill Calamity the quest will get stuck at the moment Calamity is supposed to say something.
 * In the Debt Collector quest, if you kill Caleb McCaffery, there will be a blackscreen crash every time you try to load The Strip and the autosave will become corrupted. The only known way around this is to equip an Old Cowboy Hat whenever you try to load The Strip. Not an issue on my 360 version, try restarting the game, or, if that fails, reinstalling, you may have corrupted data. Another fix is to avoid Yes Man and do no Side Bet quests, before you finish this quest.
 * During Bye Bye Love Carlitos might not spawn in Vault 21. (Check the Bye Bye Love page for a fix around this)
 * On the quest The House Always Wins If you open the Doors to Mr. House's Cryo Pod and KILL him and revert your save you will be unable to talk to him making you unable to complete the quest. (EDIT- Please clarify. On PS3, performing this sequence of events causes no apparent issues: Save->Kill Mr. House->Load Save->Speak with Mr. House)(New Author) I also did this on the X-Box 360 and it has not caused any problems. (Edit: I had no issue with this either, I saved->killed Mr. House-> loaded save because I wanted to see what happens when you kill him. (PS3)
 * (EDIT) I personally had what sounds like this problem, where dialogue appears but it's impossible to select it? I noticed that every time I loaded the game an image of my Pip-Boy screen would flash up, as if it was stuck in memory. I guessed this was due to the game believing my Pip-Boy was open for some reason. To fix this, all I had to do was open and close my Pip-Boy after loading the game and before talking to Mr. House. Hope it helps. (X360)


 * If two Mantis's fight in the Thorn they will not attack each other, ever. Pushing guards into the area doesn't do anything. Any quest related to Red Lucy in the Thorn can then not be completed. EDIT: Same thing happened with deathclaw vs 3 fire gecko. I resolved by firing and killing all creatures, Red Lucy's guards attacked me but after they were dead I could talk to Red Lucy and turn in quests. This was on PC. EDIT: If you kill one monster in the pit when hidden and with silenced weapon(try sniper rifle with silencer) guards dont attack you, and you can speak with Red Lucy again.
 * If you finish various quests (The House Always Wins, G.I. Blues, Volare! and others) you might not get the achievement. EDIT: This can be caused by using console commands, as it will lock the player out of unlocking any achievements for that play session. Closing and reopening the game fixes this.
 * During ED-E My Love when you receive a message from the Brotherhood of Steel, at the end of the message between the Brotherhood and the player, the player may be unable to move but will still receive status updates and NPCs will still function. *Xbox 360 version only, unknown if PS3 and PC versions are affected. (PC Version is affected, this particular PC player experienced it though it automatically ceased when an NPC entered and completed combat, though the Pipboy and weapons are no longer accessible afterward.)
 * In the Come Fly With Me quest, if you clear Harland of his post for Davison, Davison may attack you, regardless of whether you touched Antler or not. (PS3) Happened to me on 360 also.
 * During Come Fly With Me even if you decide to help Davison get rid of Harland, if you get attacked by a nightkin near Davison, Davison’s attitude will turn hostile and he will attack you. (New Author) This is not a bug, This is intended and is even in the strategy guide. In order to succeed in assisting Davidson, you must not kill any Nightkin in Davidsons vicinity. He will also become hostile if you kill all other nightkin in the basement under any circumstance. The idea is to ensure you can only help Davidson OR Harland not both. (New Author:PS3) If you search the "Jail" (basement) before speaking with Davison or Harland you can complete both quests. (New new Author:360) Confirmed on my game, I was able to finish both quests and everyone was happy.
 * In Come Fly With Me if, before the launch, you tell Haversam of Jason's plans for him, and convince him to go to Novac, after the launch, Haversam will still be in the basement, he'll stay in the basement, and he'll only reply to you with dialogue indicating that the launch hasn't happened yet: "Not now. It is almost time for the Great Journey!"
 * If you complete You'll Know It When It Happens after being given the quest by both Mr. House/Yesman and the NCR, the quest will not register as complete and you'll be unable to proceed down the NCR questline (the Mr. House/Yesman questlines are unaffected).(Xbox360, I turned the quest in to the NCR first, then Mr. House, and I could complete both-please verify-)
 * In Come Fly With Me, after you leave the second floor of the REPCONN building, it will be locked. Console commands can unlock the door, but otherwise you will be locked out forever and unable to complete the quest (Until a patch is issued to fix this, and similar bugs)).
 * In One for My Baby, if you allow Boone's Beret to reach 0% repair you will be unable to wear it and therefore unable to complete the quest. Quest items will not show up in the item list when you go to a merchant to have them fixed, and you can't find a second one, so the only way to replace the hat would be in the command console which will remove your ability to unlock achievements.
 * If you set up a fight between two Giant radscorpions and two Fire geckos at The Thorn they will come out and have a staring contest and not attack each other. Leaving and reentering the area does not fix this. Due to this you can not start dialog with Red Lucy. She will just say "It's time for blood. We'll talk. Find me after the fight." -Confirmed Xbox360 Also happens with several other creature types, recommend saving before each match.
 * NEW AUTHOR:  !!!!EDIT: I was able to solve this bug on the X-box 360 using the following steps:
 * Be sure to save your game. Make sure your companions are waiting outside of the Thorn. It helps if you have the Alien Blaster or similar weapon (something very powerful and relatively quiet)
 * From where you enter the Thorn, there is a ledge just above the arena floor right behind the barbed wire topped fence barricades, underneath the walking platforms, that you can jump down onto. Equip a stealth boy, crouch in the darkness, and take aim at the Red Corner Radscorpion and kill it. Stay completely still (the guards should become hostile, just relax; they should become friendly again in a few seconds). If the Blue Corner Radscorpion doesn't turn around and retreat, re-load and try again. This Radscorpion gets stuck in a corner because his door is not open.
 * Make your way to the right and drop down in front of the gate you would normally exit to leave the arena, but go inside. You should be able to walk around the arena without getting shot. Look for the other Radscorpion but DO NOT kill it. Simply open the door right next to him and immediately turn around and leave the pen. (If you stick around inside, both door and gate will automatically shut, locking you in).
 * Walk back up to Lucy and give her those damn eggs!


 * In the quest How Little We Know If you talk to Cachino after dealing with Troike but before killing Clanden, he will give the dialogue options for killing the bosses. If you say you're not ready and go kill Clanden, you will fail the mission with the associated Wild Card quest being updated with "Clanden has been dealt with" and "Go tell Yes Man that the Omertas hate you". Going back to Cachino will find him already in the room with the bosses with both bosses having drawn their guns and not moving. Speaking to him will initiate the boss dialogue/fight. (new author:360) It seems this isn't a glitch, but taking care of Clanden isn't actually necessary to the quest. It is noted in the strategy guide that if you destroy the weapons storage before dealing with Clanden, then killing him becomes optional, and you can skip to the end of the quest.
 * In the quest How Little We Know If you choose to turn Cachino in to his bosses he will be killed in the meeting. This will trigger two new quest goals with one goal being to obtain a shipment of chlorine and one about recovering a weapons shipment from fiends.  If you try to blackmail Clanden about the hooker he will not have any speech options about it and the hooker will not act like she is dead although you still get the option to perform an autopsy.
 * Sometimes in VATS, if queuing up multiple attacks with a firearm and attacking, the player will not do anything, just stand still. However, AP is not lost when going out of VATS after a few seconds. EDIT: this shouldn't be in the "Quest-specific bugs" section.
 * In the quest Poor Meat Never Makes Good Soup there appears to be a bug in this quest where you are unable to talk to either Ruby Nash and Fitz about the food supplies. This is due to a simple scripting error, which can be resolved through using the toolset. In the dialogue sections of Ruby Nash and Fitz there can be found the topics of food supplies for Camp McCarran (VFreeformMcCarranPrimmRubyNashTopic000 - only one needed to change for Ruby to work and VDialogueVegasEast1EFitzTopic006 - ...009 for Fitz). In there you only need to change every comparison-value referencing to the QuestVariable 'VFreeformMcCarran',iMessHallStatus (Value 2.00) from '==' to '>='. after that you only need to save the new modded file to your ...Fallout New Vegas\data\ folder and activate the new .esp file in your launcher and talk to each one of them and it will work fine.
 * During the quest Beyond the Beef, after checking the investigator for clues, you will get a tape saying where to meet someone. When you get to the objective, in the washroom of the swimming area in the Ultra-Lux, the person your meeting will shown up on the indicator bar in the bottom left, but will be invisible were you can not talk to him.
 * During the quest Beyond the Beef, if the PC sneaks into the members only area of the Ultra Luxe and is detected, which will happen when speaking with Mortimer after his speech, the White Gloves will become permanently hostile, regardless of how long the PC stays away from the Ultra Luxe. Not even getting Marjorie to sponsor the PC as a White Glove member has fixed this.
 * In The House Always Wins II when you try to go to the Lucky 38 to talk to Mr. House the robots attack you and the quest fails automatically. This apparently doesn't happen to everyone.
 * During the quest Young Hearts Jack may not be anywhere at Nellis AFB. Following the compass arrow will eventually lead you to Black Rock Mountain to a rock face just past the satellite dishes but Jack is still not to be found. Companions may some times disappear into this same Rock, but will usually reappear after fast travel.
 * This seems to happen if you start the quest prior to completing Volare!, then try finishing it afterward.
 * Loyal also disappears from Nellis after Volare!, making Old School Ghoul quest undoable.
 * During the quest All or Nothing, at the point where the Boomers are supposed to show up (after fighting 2 groups of fiends), the game crashes. This happens regardless of whether you help House, NCR or yourself, regardless of what you are carrying and regardless of your companions.  (Steam version, definitely not a hardware issue, latest drivers and patches as of 11/11/10 - only some copies of the game)
 * During I Fought the Law even if you successfully complete the siege on the prison and get NCR back in control Mr. New Vegas will still say the siege failed on Radio New Vegas. This also affects the ending involving the NCRCF in which it states the NCR never retook the Prison.
 * During the game, a glitch may occur if you do the following: Kill Ceaser in his fort, and then go kill Benny. Because you can receive a platinum chip from both characters, killing them both will give you two.
 * After completing Eyesight to the Blind by informing McNamara the device has been installed, he will instruct you on the use of power armor. After which the player will not be able to move in any direction, but can only look up and down. Speaking with McNamara again, waiting, or reloading will not fix glitch.
 * In the unmarked quest A Two-Bit Hustler you are asked to provide evidence that Keith is cheating at cards and selling drugs. Once you provide this information to Captain Parker he will enter Aerotech Suite 200 and confront keith.  Captain Parker will begin a dialog with him.  If Keith was awoken by  Captain Parker he will go back to sleep as soon as the conversation is over.  Captain Parker, who wants to kill Keith for insulting his wife, will spin around in circles with his gun drawn above the sleeping Keith.  You can correct this by talking to Keith.  As soon as Keith gets up off his bed, Captain Parker will kill him.

Location-specific bugs
For location-specific bugs, please see the respective location article page.
 * In the Lucky 38 Presidential Suite the terminal used for purchasing extra features does not have the items properly mapped and you must click of to the right of the right of the item to select it. EDIT: Or you can just close the Computer and the using the standard menu.
 * After upgrading the Lucky 38 Presidential Suite the containers by the workbench can reset causing you to lose any items placed there.
 * North of the cove location towards the south, standing on the highest rock will result in becoming stuck and unable to move.
 * At the Gomorrah, the dealer may talk to a Gomorrah floor manager like he is a visitor of the casino
 * It's possible to go outside of the map due to a ledge southeast of Morning Star Cavern.
 * In No-Bark's house, if you jump in between the fridge, the wall, and the bed area, you will be stuck. Reloading the last save or using the TCL console command are the only ways to get out.
 * In the rail way path, at the south of the Boomer "mortar town"(very hard locked door) the path has about 6 ghouls and traps. There is a small side room and the stairs are fall through. You, or anything else cannot cross it.
 * After upgrading Mr. House's Securitrons, the gate to the Strip is locked by key and the guarding securitrons aren't upgraded.
 * At Repconn Headquarters, it is possible despite gaining an Executive Level pass from hacking Isley's computer, that the robots in attendance upstairs will not acknowlege the pass and the alarm will be sounded after 30 seconds. Verified on PS3 and XBox 360.
 * At the Brotherhood of Steel's Hidden Valley Bunker, you can possibly become stuck within the bunker. The door in Level 1 will be locked and you will need a key to open it.
 * When making your way to Nellis through the train tunnel, half way through there's a room to the side but when you try to enter it theres a hole in the map, you fall through and go back to were you came in.
 * At the NCR Military Police HQ, prisoners in cells (If attacked) can open the cells to their freedom.
 * At HELIOS One when you walk out the door to the solar panels sometimes you will see Old Lady Gibson, her dogs, and molerats or any combination of these. If you have a companion they might accidentally hit Old Lady Gibson when they are attacking the molerats and they will kill her. In addition, a collection of invisible barrels can also load, causing collision noises as you walk.EDIT(Devon of Granite) this has also happened to me (X-Box 360). The only way to not kill the dogs, molerats, and/or Old Lady Gibson is to load the autosave created by opening the door, or an older save. NOTE: This does not happen every time.
 * At New Vegas Medical Clinic, entering at night requires you to pick an Average lock. After picking the lock and entering the clinic, approaching the door from the inside can sometimes display the message 'Locked Door: Average. [Pick lock]'. Pressing 'A' (Xbox 360) does not enter the lockpick screen, instead it takes you to a frozen loading screen. To fix, reset the 360 and load prior save.
 * At the NCR outpost west of Primm the tent with no npcs in it well nearly always crash upon attempted exit. Only work around is to load a save outside the tent and never go in it.
 * at the Mojave Drive-In, there is a scene where a prospector is being attacked by many mole-rats (unsure if scripted specifically or randomly). Even if you are quick enough to save him from the creatures, he will disappear almost immediately after.
 * After you enter the Fortification hill and speak to Caesar about Benny and Platinum chip you will have the option to go on and enter the bunker in which you will either destroy securitron army or upgrade them for your own use, after this done you can either go back to Caesar or go on to do other quests outside this location. Only theres a problem, When you get to Cottonwood gate to leave the fort it will not allow you to leave. The only way past this I found was to jump to the loaction outside of the fort.

Exploits
Please see Fallout: New Vegas exploits.

General solutions

 * Leave and re-enter the area.
 * Load a save from before the glitch occurred.
 * Exit the game, restart the game, and load a save from before the glitch occurred.
 * PC users may be able to fix some issues by using console commands.

Clipping

 * Clipping (items and actors getting stuck in the ground or in other items) is a common problem.
 * The Courier may be pushed through objects, such as the ground, and launched forwards.
 * Sometimes, if you pick up an object from a table or other surface, all other objects on it will fall through the table.
 * Some clothing have bad clipping problems such as the weapons going through the armour.

Crashing, freezing and slowdowns
Crashes and freezes may happen occasionally to anyone. Crashes and freezes are only notable when they are repeatable (e.g. they happen under the same set of circumstances often). If the crash only occurs on one particular save, then the save itself is most likely the source of the problem. Please verify that crashes and freezes are repeatable on more than one save game before reporting.
 * Crashes often when you near completion of the game.
 * Crashes in VATS are somewhat common.
 * Crashing or freezing when entering or exiting areas is somewhat common.
 * Crashing or freezing upon entering The Strip is fairly common.
 * A Sputtering slowdown followed by a crash.
 * Severe slowdowns are occurring on all platforms. Restarting your system may help.
 * Turning the pip-boy radio off and leaving it off seems to help quite a bit. Try it if nothing else seems to help.
 * The game freezes when repairing/wearing/unwearing the NCR Bandoleer Armor found in the tent next to Lieutenant Hayes' Tent. Don't even go near it. This also happens in the Supply Shack at Camp McCarran. This may be due to the fact that they're of the same condition, and may happen with other stackable items as well.
 * If one saves at the beginning of the game while editing your character the Level up system can crash.
 * After entering the Hidden Valley Bunker. In the main office, after handing over your Weapons, Clothes and Ammo. (Occured during ED-E My Love quest) (PC and Xbox 360). (Workaround: Don't bring any companions inside the bunker with you during the "strip")
 * Attempting to fire Euclid's C-Finder at any time with the Heave Ho Perk. (After arming the Archimedes-II) (360)
 * At any time the game will freeze up and crash followed by a message box stating that required downloadable content is not present, and then continuing to load will bring up another message saying selected save device is not present.

General NPC bugs

 * The NCR Rangers that follow you when you have a bad reputation with the NCR will hunt you down in locations they should not have access to, such as the brotherhood of steel base.
 * Certain NCR personnel will become hostile toward you, despite having your infamy cleared and being "Liked" by them again.
 * After calling an NCR Ranger to assist you, despite them saying 'Ranger at the Ready' I have had to actually approach and talk to the Ranger, having them repeat 'Ranger at the Ready' to get them to follow my party.
 * When attempting the quest Still in the Dark I went to talk to Elder McNarmara about the 3 Scouts and upon entering Level 2 of Hidden Valley an Initiate ran towards the command center. Upon entering the command center McNarmara stands up and equips his Laser RCW, he then proceeds to run in place towards Paladin Hardin's room and it is impossible to start conversation with him. Every NPC after this is frozen including followers not in the party.
 * Sometimes items placed into a followers inventory are not listed making them inaccessible.
 * It is possible for NPCs present in the Atomic Wrangler to randomly aggro an unseen enemy, running to a room on the second floor and staying there. Leaving and re-entering the building may fix this.
 * Ed-E may sometimes, upon waking up from being unconscious, make a sound as if he is slamming into metal and then disappear unable to be brought back even when fast traveling. You will not be able recruit Rex later on if this happens.
 * game crashes/console freezes after trading with some wandering merchants, either upon exiting transaction screen, or when trying to save immediately after, or leaving the environment. In one particularly bad case, it seems that the merchant would still have the stock you just bought from him when you go to trade again. This might be related to the crash, if one were to re-buy the same item in this way.

Engine Bugs

 * Control and HUD loss on reload from save. Known to happen on all three Gamebryo Engine games.
 * If for some reason the engine hangs for a while, the terrain thread can get stuck which means A) the terrain will never update again, leading to the player being able to access the lower LODs B) the thread never closes which means the game hangs on exit

Radio-related bugs

 * Subtle audio-normalization issues on the radio, making some songs noticeably quieter than the announcer (Mr. New Vegas).
 * Some songs played much more often than others. (Seems to only be radio stations with an announcer, Mojave Music Radio appears to randomize correctly)
 * A noticeable distortion is present in Mr. New Vegas' speech when in Freeside or the New Vegas Strip caused by the ambient sounds.

Animation bugs

 * Sometimes the players hands will grow in size for no reason but this can be corrected by realoading the game.
 * Hitting a stack of books using power fist in the docs bedroom in his house in goodspring will cause them to bleed (like when you hit an NPC with it).
 * When putting away pistols if you're running the pistol will enter your characters back and stay there until you draw your weapon again, if you hold still while holstering your weapon it will go to your side as normal.
 * When equipped with a two-handed gun in first-person mode, the weapon often clips mid-view, distorts, and slides to the top of the screen and behind the player's perspective.
 * Zooming in with Guns equipped with the scope mod sometimes results in a black screen with a hack computer screen.
 * Zooming in and quicksaving the game and then loading the game will cause the zoomed-in view to overlay the first-person view, you will be able to move around normally but most of the screen will be covered. (PC)
 * When you kill something and the cinematic death is presented, pressing and holding the 3rd person button and then rotating the camera will cause you to spin while you gun stays in place. The view stays in 1st person and you can't switch to third.  You can still move and shoot but not aim down the sights.
 * Looking through binoculars sometimes results in a black screen with a hack computer screen but can be fixed by getting out of the game completly and back in. (xbox 360)
 * Sometimes when telling a follower to switch back from melee to ranged will result in their ranged weapon to be holstered where their melee weapon was. (Example: Boone unequipping his machete and equipping his rifle. The rifle will be at his hip instead of on his back).
 * Some caravan card games may not load up a screen, but rather load up the options to choose cards. The screen will remain with you looking at your opponent.
 * When wearing the Prostitute Outfit and straffing to the left, the arm will twist and morph, causing the player's skin to show through the clothing.
 * Occasionally, some NPC's heads will do an 'exorcist', or will turn completely upside down, being near their chest. This is extremely rare, but the most notable person to do this is Antony ( This bug can be solved changing the screen texture settings in "PAUSE" menu, tested by me).
 * Sometimes, your fingers will 'break', and your index finger will bend and partially clip through itself.
 * Many NPCs seem to sit about 2 feet to the left or right of chairs instead of actually in the chair in several places throughout the game. (PS3)
 * Sometimes, when a character is talking, their mouth won't move or there mouth will move when they aren't talking anymore. This happens (generally) when a message pops up on the screen during a conversation.
 * Sometimes whilst sitting with Brotherhood T-51b power armor the shoulder plates start turning upside down
 * When activating a computer console for use, the screen becomes blurry, rendering the terminals unusable, but you can hear the typing on the computer as if nothing is wrong. Players can still back out from the screen.
 * Numerous NPC's will sit down at a dining table or empty desk and begin to type on a computer that isn't there. You can hear the keys and their fingers will move, but no computer will ever appear in front of them. Note that this has occured in locations where a computer isn't present. (XBox 360)

Weapon Bugs

 * Many weapons, when modded will block the target reticule and obscure all view when aimed if "True Iron Sights" is disabled.


 * Anything related to the hot-key functionality will cause the PS3 to hang, requiring a hard reset. Including: using R2 to assign a weapon to the D-pad hot-key from the pip-boy interface, using the D-pad to change weapons.
 * After reloading a pump-style or drum shotgun the fire trigger may not work from 0 to 60 sec [not good in combat as you can imagine] after the reload. Also occurs with the Cowboy Repeater rifle. Solution: Do not let the ammo in your gun run out, i.e., reload before it's absolutely required to fire another shot. EDIT: performing a quick 360-degree spin (on PC, at least) allows the weapon to be fired once again. Someone please confirm other platforms.
 * If you use a lever-action or revolver that you have to reload bullet by bullet. This may help click your ammo switch button real fast till your back at the ammo you was using. You now only reload one bullet and ta-da.
 * The Weathered 10mm pistol is missing a mesh, that is, a graphics file needed to display the gun correctly with gun mods added. Consequently, when you add mods to the gun, you end up with severe visual distortions. A couple examples below:


 * when using the Grenade Machinegun it is impossible to kill a mole rat with high-explosive ammo ( needs verification)


 * The Anti-Materiel Rifle will cause people to spontaneously combust if you target them in V.A.T.S, then cancel before firing with Incendiary rounds equipped.
 * the 9mm AP ammo is displayed as +P, just a typing bug. This isn't a typing error, +P is a type of 9mm ammunition which is loaded to higher pressures and thus has more kinetic energy.
 * I'm not sure of the scope or range of this bug, but I had Boone equipped with a Riot Shotgun and gave him ammo, then realized that when he ran out of ammo, the game would lock up, not sure if he was unable to switch weapons or what, but I had a save where he had 4 12ga rounds left, and every time we engaged an enemy, the game would lock up, requiring a hard reset. This happened with multiple enemies, including Radscorpions in Radscorpion Gulch, Caesar's Legion, and Cazadores, if he fires the last of his rounds, the game locks up. Needs verification. ← Teddybear.
 * Aiming down the sight of any weapon may cause a blank terminal screen to come up instead of the scope.
 * So far this has only happened to me at the NCRCF: After entering attack commands in VATS, my character stood idle, w/o firing and only taking damage. This lasted about 30-40 seconds, and happened twice, but only at this location so far.Musicfeind2001 02:06, November 12, 2010 (UTC) Verified on the PC as well, in random locations throughout the game.
 * whenever i shoot the controller turns off meaning i have to turn on my controller again verified on xbox360

Barter system bugs

 * The vendor's name is blank when the barter screen is first opened. If the category of the vendor's items is changed, when you cycle back to the vendor's name, it is now displayed.
 * When purchasing any items from Blake at The Crimson Caravan Company the game will freeze or suffer a severe slowdown immediately after the transaction is complete. Has happened many times and occurs occasionally with other merchants. Occurs most often however with Blake.
 * Selling a modded weapon, and then subsequently trying to buy back the weapon, will result in the purchasing of a different form of the weapon(if it is stocked). Example: Trying to buy back an extended mag 10mm Pistol while other 10mm Pistols are present will result in the purchase of the unmodified weapons first. Purchasing all weapons did not solve this problem, as the modded weapon would not be transferred, though caps were lost
 * If the user abuses the infinite caps glitch with a vendor, the item the player is buying may duplicate in their, or the vendor's inventory. If the item duplicates in the players' inventory and the player is already carrying an item of that type, all the duplicates will not be listed. However, once the player drops or stores that item, the duplicates will appear.
 * When repeatedly buying items from vendors, the item the player is buying may simply disappear when the player accepts the trade. The player will still be charged for the purchase, but never receives the item.
 * Old Lady Gibson may stop giving you caps for any items that you sell to her. The items will disappear from your inventory, but no caps will appear in their place. The items will not appear in her sell screen or inventory, either.
 * When bartering with a travelling merchant, the barter system may freeze upon finalizing a transaction when purchasing one or more cards. It is quite likely that this only occurs when trying to purchase a card that you already have one of within your inventory.

Schematics/Workbench Bugs

 * If you obtain the Rock-it Launcher Schematics or Food Recipes, they will not show up in the workbench or campfire crafting menu.

PC-specific bugs and issues
Stuttering, crashing, freezing, and slow-down issues are often hardware- and/or software-related. Please visit the Bethesda forums for information regarding these issues. In particular, read through the stickied threads at the top of the forum page.


 * Strange black and white boxes appearing at long view range with Nvida GTX 4xx cards in singular, and many SLI setups. I believe it's a Driver Issue--Omega. (may be fixed by latest GeForce 260.99 driver)


 * Indoor HDR lighting will frequently flicker in areas close to light beams and other nondescript areas. This bug is intensified when the PipBoy light is on. (verified on Radeon HD 4670, on window mode, full screen and using crossfire).

Inventory Bugs

 * When first accessing a merchant's inventory, the merchant's name is not initially displayed as the inventory heading. After scrolling through the available item categories / headings (Weapons, Apparel, etc.) and back to the master list, the merchant's name appears.
 * Throwing Spears often stack incorrectly when moving to / from companion inventory and containers. For example, while you may have 30 Throwing Spears in your inventory, they will appear as 10.  Attempting to take all of them resulted in 3 being removed from the stack and 27 remaining. This has also been seen with dynamite and a few types of armor/helmets.
 * When removing a weapon from several of the same type in your inventory, a "modded" weapon (as per the mod ability present in the game, not one added by a game mod) will lose the (+) indicating that it is modified. For example, I have five Varmint Rifles in my inventory, one, with a scope and silencer, indicates the presence of modifications with a "+" appended to its name.  After removing one of the "un-modded" Varmint Rifles from inventory, the "+" disappears from the weapon's title. Also present in bartering. Also happens when moving modded weapons to or from storage containers, such as the cabinet in your hotel room in Novac; in this instance at least it is temporary, and you can still see attached mods by holding the mouse over the modded weapon.
 * Motor-Runner's helmet cannot be removed after turning in the quest to General Hsu. Same goes for the Van Graff armor during the quest Birds of a Feather. I was able to remove the Van Graff armor only after killing all of them.
 * Items in all inventories (yours, companions, merchants and containers) will “hide” behind like items. Seen multiple times with many different items but two specific examples are:  Throwing Spears, inventory said 24 while in locker, upon removing the 24 another 40 appeared in the inventory.  While gambling at Vicky and Vance’s casino I was awarded a set of Leather Armor, Reinforced.  When checking inventory it only showed the set I was wearing, however after dropping that set the additional set appeared.
 * Numerous quest related items are not removed from your inventory once the quest has been completed and cannot be dropped. ie. Distinctive cigarette butts, Engraved Cigarette Lighter, Empty Hydra Syringe, Food Additive, Karls Journal and many others.  Other items remain in inventory stating they are quest related, yet no known quest exists.  ie. Camp Guardian Log pages.  Additionally items like the Rebreather and NCR Emergency Radio, though they may still be of use, you may simply wish to not have them in your inventory but they cannot be removed.

Graphics glitches

 * Black and/or White flashes may appear on screen at almost anytime during gameplay. These flashes seem sometimes to be part of the environment, staying in one spot as you move, and sometimes part of the HUD, moving with your HUD. This can usually be fixed by updating your graphics drivers, if this does not work setting Anti-Alias to NONE always works.


 * It seems the problem described above happens when a moded weapon is held in the players personal inventory with an un-moded weapon of the same type with better condition than the moded weapon. The weapons "stack" and cannot be accessed in the players inventory at the same time.


 * When crouched and holding a rifle while in first person mode, your arms will occasionally appear to be above your head as if the camera moved down your chest and arms did not follow. It can be solved by standing and crouching one or more times. Additionally, the gun seems to disappear altogether from view, even when holstered and redrawn. It can be solved sometimes by switching view to third person and back.
