Fallout: New Vegas bugs

General advice and notes

 * 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.

Bethesda's support page
Bethesda's FNV support page offers many simple solutions to common problems.

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.

Gameplay bugs

 * (360/PS3) 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)(Turning on then off the pip boy light can fix this on PS3 & Xbox)
 * (PC/360) Certain characters will sometimes (rarely) change "Race" settings, for example from "White" to "African-American" or "Asian". They keep the same voice and conversation options, only their appearance changes. (Examples include Alexander the Gun-Runner at 188 Trading Post and the owner of the Dino-Bite shop in Novac).
 * (PC/PS3) Switching weapons will sometimes automatically and inexplicably change the ammo type to default, even if a different ammo had been loaded into a weapon.
 * (PC/360/PS3) 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 the exception of a few, such as "Ammo Box, Microfusion Cells", which are correctly added as ammo immediately. Note: In hardcore mode this 'bug' is actually a benefit as a box of 250 x 5.56mm Surplus rounds weighs only 5 WP as opposed to 250 x 0.03 = 7.5 WP so it's quite handy to carry around as a backup, only to be used if you tap out on the good stuff.
 * (PC/360/PS3) NPCs will comment on your companion as if they were next to you, even if that companion was set to "wait" in an entirely different area. -confirmed on ps3-
 * (PC/360 Versions) In some instances when the player turns on their Pip-Boy's light, the entire sky may glare up, regardless if day or night.
 * (360/PS3) For unknown reasons, After a certain point, game freezes whenever hot key is accessed, even when attempting to change hot key items via pipboy, game will still freeze.
 * (360) Sometimes when entering VATS game freezes, possibly due to numerous enemies/large quantity of data being processed. The game may unfreeze at some times, others not, requiring console restart.
 * (PC/360/PS3) Sometimes,when fighting against any enemy in the game,you'll notice (when being hit or shot) that your character's voice will sound like a woman,even though you're playing with a male character. This doesn't happen with female characters. -confirmed on ps3-
 * (PC/360) In camp McCarran when entering with ED-E and standing next to the tents in the courtyard upon talking to the soldiers there, sometimes the NCR soldiers will spontaneously attack and shoot ED-E unconcious. Once ED-E regains conciousness, they will attack again and this continues on. It does however not trigger a hostile reaction on you or any other companion. But continues no matter what quest you have completed in there, as tested out so far.
 * (PC Version) NPCs will walk into walls and may get stuck in one. Talking to them, or attacking (Via Explosives or parts of their body extruding from walls) helps sometimes.
 * (360) When entering places such as camps, buildings, doors, the game may freeze.
 * In many locales (though especially The Strip) The entrance/exit door may say it requires a key. Which in some instances makes it extremely difficult if not impossible to gain entrance or leave an area.
 * (360) The exp bar may not increase, or show, even when gaining exp from enemies, terminals, locks, or discovering locations.
 * (PS3) Some speech checks will not reward any exp, and remain dialogue choices every time.
 * (PS3) Very Rarely, guns will fire on their own until out of ammo when equipped from the Pip-Boy. Can be fixed by console restart. (fixed by equipping assault carbine -needs confirmation-)
 * (360) In Nellis Airforce Base, if you are a male character, running into NPC's (no dialog - run into them or clip them on the way past) results in them saying "Watch where you're going lady."
 * (PS3) Sometimes NPC's voices will be different to what they are when in dialogue.
 * (360) When you have an upgraded as well as a standard 9mm Submachine Gun, moving them in and out of a container might make the standard one disappear (it reappears upon removing the other one) or be "magically" repaired to full condition.
 * (PC/360/PS3) During moments of intense action, on screen, the game may not recognize buttons presses making it hard to change weapons.
 * (360) After changing areas the camera became fixed and the auto save file would not allow the problem to be fixed, the controller itself was fine tested on the Pipboy map, entering a new area did not fix the problem either and then was stuck since none of the doors could be looked at.
 * (360) Upon teleporting and autosaving, the brightness of the display becomes very dark and blurry, effect is permanent on autosave.
 * (PC) Upon drinking large quantities of Alcohol (Scotch, Whiskey, Vodka etc) the effect labelled 'Alcohol' on your Pip-Boy (INT -2, STR +2, CHR +2) may not disappear. Could correlate with the use of Fixer or Chem withdrawal while the effect still exists.

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.
 * When visiting the pitstop outside Nipton, a number of friendly compass ghosts showed up. When approached, one was labelled Raven and was collidible but not interactive or visible. Some appeared to be under the terrain.

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


 * 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 pot is needed. This was found on the Xbox and PC version, unknown if PS3 is affected. EDIT (different author): I was able to fix the food processor when carrying an extra Pan(Pot?) in my inventory (2 instead of 1). Upon fixing the processor, only 1 Pan(Pot?) was removed from my inventory, however.
 * During I Put a Spell on You the bomb will explode even if disarmed.
 * If you do Wang Dang Atomic Tango quest before picking up Debt Collector quest, talking to Santiago will automatically add the debt collector quest, but the dialog and the last stage of the Debt Collector quest get messed up.
 * During I Could Make You Care you can explore the terminal stations at the brotherhood bunker. Scribe Ibsen will ask your assistance in isolating a virus on the terminals. There are two methods to complete this mini-quest, a normal attempt at finding the virus on the terminals and a speech check of 70 to partition the terminals. The speech check of 70 method is bugged where all three terminals are found and partitioned but the quest does not complete (not confirmed on PC version) EDIT (different author) This didn't happen to me on the PC version. EDIT (new author), I have three terminals stuck on the "check partition" status and I can't isolate the virus no matter which other terminals I check.
 * 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.
 * 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 that Station. It will remain a quest objective until you return to Rayes where you can finish the quest.
 * Mr. New Vegas' radio news announcements do not properly reflect the conclusion of I Fought the Law if the player sided with the NCR instead of the Powder Gangers.
 * 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".
 * During Guess Who I Saw Today, before letting Doctor Henry experiment Lily Bowen, when you kill Calamity the quest will get stuck at the moment Calamity is supposed to say something, the quest will get stuck and you cannot complete it.
 * 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.
 * During Bye Bye Love Carlitos might now 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.
 * 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.
 * (PC Version) If you finish various quests (The House Always Wins, G.I. Blues, Volare! and others) you might not get the achievement.
 * 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.
 * 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) (New Author)This happens Because you have killed all of the Enemies before speaking with Davison. To get credit for both portions you must talk with Davison before assisting Harland
 * During Come Fly With Me even if you decide to help Davison to get rid of Harland, if you get attacked by a nightskin near Davison, Davison’s attitude will turn hostile and he will attack you.
 * 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).
 * 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.
 * (360) If you set up a fight between two Giant radscorpions and two Fire gecko (Fallout: New Vegas)s 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."
 * (PC) In the quest How Little We Know If you talk to Chachino 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.

Location-specific bugs
For location-specific bugs, please see the respective location article page.
 * (PS3) going anywhere or speaking to anyone on the Las Vegas Strip causes an immediate freeze which requires a reboot of the PS3. Also the vegas strip can only be entered from the Monorail or the game goes to a black screen and crashes.  Unable to determine what caused the glitch, but it appears to be incurable.  Saving and reloading, loading earlier games, etc. nothing helps and you cannot proceed with the game.
 * At Helios One, just north of scrap yard when going out the back door (to the solar panels). Old Lady Gibson and her dogs will spawn and attack you. Reloading the autosave will fix this.
 * (PC Version) 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.
 * An ammo box inside a tent at Helios One shows a computer hack screen over the normal lockpick mini-game screen while hacking. Picking the lock is still possible but more of a challenge. The same bug occurs on a locked door next to a computer terminal in Vault 3, reloading a save game does not rectify but quitting the game completely and reloading does.
 * At Buffalo Bill's Casino and Hotel in Primm, the computer terminal will blur w/sound but the screen will not appear. At the Lockpick later on on the first floor the computer screen will appear over the lockpick interface. (Resolved with a restart of the console, reverting a save did not fix)
 * 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 the city Primm, saving the deputy from the escaped convicts. The deputy has appeared running halfway through the ceiling. (360 version) Confirmed in PS3 version too
 * When loading in Freeside on PC version IE entering/exiting buildings or loading save; game will eject to black screen and fail, requiring restart. Immediately saving after load seems to help.
 * In Nipton, in certain circumstances the Powder gangers might be standing against the crosses and when talked to they jump on the crosses and crucify themselves! Video and instructions: http://www.youtube.com/watch?v=bcWXEpovC0Y
 * On the Xbox 360 & PS3 version, sometimes entering The Strip will cause the screen to go black and the game to crash. This will corrupt your auto save.
 * 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 Nellis Hangars, the male child NPCs might use female voices instead of male voices.
 * In Freeside, after killing the Giant rat that the children are chasing, if spoken to, both children will say "Thanks," in the male's voice, even though one is female.
 * In the 188 Trading Post, Michelle's voice may be altered when talking to her. (PS3)
 * In the administrative/headquarter building of Mojave Outpost, there is a NCR Trooper who is typing. However, there is no computer present. (PC/PS3)
 * (XBOX 360 & PC) In Hidden Valley, Bark Scorpions attack on the surface. Sometimes, one or two of these can be half clipped in the ground, bodies under the surface but stingers (tails) above.  Target these and you will see that the parts underground always have a 0% chance, but the part above ground (the stinger) is ok.  Shooting this off however will display the death animation scene, the tail will stay above ground and the scorpion body will fall forever through the ground and off the map.  Luckily, after the death scene the game returns to your view. EDIT (new author) This is not a location specific bug. This bug effects all types of Radscorpions and Bark Scorpions at all locations they can be found that aren't completely flat.
 * At Gomorrah, if you refuse to give your guns and leave, you will be held stationary and unable to do anything upon entering again. The only way to get out is to load a previous save.
 * Just northeast of the Lucky Jim Mine, there is an invisible barrier preventing you from climbing a hill. LuckyJimMineBlockage.png
 * In Primm, at the casino, Vikki and Vance, it's possible to break the bank and then everytime you cash in your chips, it pays you in caps, but you keep the chips. (Infinite Caps Glitch) Don't know if it happens everytime you break the bank there.EDIT (New Author)You don't have to break the bank, it happens anytime you cash in your chips you keep the chips.
 * 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.
 * 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).

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 PC 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
 * Players can also spot floating objects. For example; a fork in cottonwood grove,floating toolbox in Nellis Hangers by a workbench, floating powder charge (S,SE of NCR correctional Facility,).
 * If a Mister Gutsy is killed by having one of its eyes shot, it will leave 2 small pieces of them floating in mid-air.

Crashing, freezing and slowdowns
While moving anywhere to any position by walking/running, the game will slow down/crash. This happens at any point in the game. 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.
 * Unknown cause, but in The Tops and Ultra-Luxe casinos, the game freezes after the last line of dialogue "Enjoy your stay" when handing over weapons to the greeters. Taking the violent approach and leaving allows the game to keep running, but may cause permanent relationship damage with that casino. (Works fine here on 360)
 * Severe slowdowns are occurring on all platforms. Restarting your system may help.
 * On the Playstation 3 and xbox version. Repairing two "NCR Bandoleer Armors" at the same condition will always result in a freeze
 * In Primm, there are some tents that the NCR forces stationed there use as their field HQ. In one of the tents, it is empty except for a bedroll and a shelf with a few containers. One of the containers holds two NCR facemasks. The game will crash fairly soon after trying to use these masks in any way after picking them up. Combining them to repair them causes the item to disappear from your inventory. The only safe method to interact with them seems to be to avoid that tent entirely or drop the masks after finding them. This bug was found on the Xbox 360 version and verified on the PS3; also when wearing or repairing NCR Trooper Armor.
 * While playing, it is not uncommon to have a "black screen" crash upon exiting a building. The exact cause of this is unknown, but there is a quick work around. The player simply needs to eject the disc from the PS3/360 and then restart the game once it returns to the main dashboard menu/XMB. So far this is the only known way to prevent corrupted save data.
 * If you get this while trying to enter the Strip and have done all the quests at the Atomic Wrangler, equipping an Old cowboy hat can allow you to enter the Strip.
 * If one saves at the beginning of the game while editing your character the Level up system can crash.
 * Upon load up, the screen may turn into vertical lines of black and orangish colors, and your Xbox will freeze up.Game_freeze.jpg
 * Confirmed cause unknown, there is a bug where entering the New Vegas Strip will cause the game to freeze and the autosave to be corrupted.
 * Occasionally, when attempting to Quit from the Pause menu, game will freeze after "Loading DLC" notice pops up. (Observed with Classic Pack pre-order bonus)
 * PS3 (possibly all platforms): A crash to XMB During the quest Beyond the Beef is possible. If you go the quest route where you serve fake human meat at the banquet and bouncers have gone hostile before you talk to Mortimer to expose his plan, the bouncers will flag non-hostile, but some generic White Glove patrons will duplicate standing on their seats, Marjorie may disappear entirely, and the game will crash out about a minute after Mortimer escapes. The easiest way to avoid this (short of going a different quest route) is to sneak into the room in the first place, sneak up behind Mortimer and stand up and talk to him the moment he finishes his speech.
 * (XBOX360) For no reason at all, after the PC meets Caesar and leaves, every time they try to return to The Fort, the game crashes while loading. Possibly on all systems as well.
 * PS3 occasional crash when opening some mailboxes

General NPC bugs

 * When you enter a casino with Boone as a companion they take all your weapons and when you leave they give them back along with Boone's Rifle. When you try to give it back to him it will not show up in your inventory and if you drop it you can't pick it back up(PS3).
 * 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.
 * Sometimes, NPCs can be found typing on broken computers. Additionally they will type in mid-air because the broken computer is not aligned correctly with their hands. The sounds of keys clattering will still be heard though.
 * A few times, specifically when exiting Helios One to the courtyard with the solar panels, a loud crashing sound happens, and then Old Lady Gibson and her pack of dogs spawned in the doorway. One time this happened, she became hostile and Boone killed her and the dogs.
 * Sometimes after calling in help with the NCR Emergency Radio and dismissing the Ranger, you can find them again outside the door to Camp McCarran. The Ranger will then follow you again as if you had used the radio, but they cannot be dismissed.  This is troublesome because they will sometimes attack quest targets that are not necessarily friendly with the NCR (such as the Strange Man you meet for the quest Birds of a Feather).  To get rid of the Ranger, I had to lure her into a fight where she would die and I could escape.  (Simply killing her yourself will lose you reputation with the NCR). (360)
 * On rare occasions upon speaking with key characters of the 'Come Fly With Me' quest, for the first time, it may go into dialogue mode as you should, but he will have nothing to say, and you will be presented with no options in the speech menu, ultimately leaving you stuck, having to reload a previous file. (360 Confirmed)
 * (may not be a common issue, but) After becoming aligned with the NCR, you may encounter a trio of dogs at Helios One identified as NCR guard dogs that will attack you for no reason.

Missing NPC bugs

 * If you give Arcade Gannon the Wait command and leave the area (i.e. fast travel) he can disappear from the location from where you left him and will not be back in the location where you recruited him. You also cannot change your Humanoid companion while this is happening. (Xbox 360)
 * If you tell ED-E to return to Primm from anywhere but very near Primm, he may disappear entirely. This does not, however, lock your robot companion slot as the leave confirmation has already gone through. (PS3)
 * If you wait 24 hours in the shop in Primm he may return.
 * Carlitos does not appear in Vault 21 in the quest Bye Bye Love.
 * If ED-E leaves of its own choosing after being stuck in an area for a while or being told to wait, ED-E may become hostile to everyone (You NPCs etc) when you go back to Primm. Reloading old saves may fix this. To prevent this bug from occurring, you should keep your eyes on ED-E at all times when travelling down narrow paths.

Engine Bugs
When aiming down the sights, when you shoot, it will not hit the enemy.
 * Control and HUD loss on reload from save. Known to happen on all three Gamebryo Engine games.
 * (Seen on Xbox 360) Hacking in Bison Steve's casino sees the gameworld blur, then brings up only the audio of the hacking minigame. This can be repaired by quitting to the console dashboard and restarting and reloading, but is likely to recur.  Similarly, attempting to lockpick in Bison Steve's may result in a blank hacking minigame console appearing instead of the correct minigame.  Again, this can be solved by restarting and reloading, but again may recur. (Did not happen for me on Xbox 360.  Seconded; two locks picked and one terminal hacked with no glitch.)
 * At times when unholstering your weapon the attempting to fire it using iron sites the weapon will not fire in spite of clicking the mouse button to do so. Dropping your weapon to hip fire then back to iron sites will allow you to fire again
 * After reloading a pump-style or drum shotgun the fire trigger may not work from 0 to 60 sec (avg. 3-5) [not good in combat as you can imagine] after the reload for the PS3. Solution: Do not let the ammo in your gun run out, ie, reload before its absolutely necessary to fire another shot.
 * 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)

Animation bugs
Sometimes when speaking to people, their mouth won't move.
 * When putting away pistols (9mm and such) 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.
 * 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).
 * When using the Varmint Rifle (possibly others) with the night vision scope, if you get a cinematic kill while looking down the sights (not in VATS), the cinematic camera will be in night vision if you continue to hold the left trigger
 * When in casinos, the dealers at blackjack tables may be passing out and collecting invisible cards. This happens when you watch the dealers, but do not play
 * 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.
 * Occasionally when a follower is given a non-default weapon and uses it in combat, they may get "stuck" while reloading and just stand there constantly looping the reload animation. Telling the follower to switch to melee and then back to ranged breaks the loop and allows the player to continue as normal. (Observed on Xbox 360 with Cass using a Cowboy Repeater and Lever-Action Shotgun)
 * Using weapons like the .357 Revolver, Lever-action shotgun, Cowboy Repeater or any weapon that uses individual round reloading can cause a bug that prevents the player from performing any action temporarily. This is caused by moving whilst reloading - once the animation stops on the reload, the game will loop an animation for an additional few seconds until it sees the animation as 'done'. For example, reloading the .357 Revolver while running forward will bug the player after the reload, not allowing the player to shoot, activate anything in the environment, or use their Pipboy. The method of reloading may not be related as this bug has been experienced using the magazine loaded Sniper Rifle.
 * The Silenced .22 pistol in third person mode has one expended round constantly above the hammer in mid air.
 * If you make a save file while being scoped in with the Anti-Material rifle, upon load the texture will overlay the player's view even when not zoomed in. One way to fix this is to zoom in with a different rifle and zoom out, however this doesn't work in all cases. (Confirmed 360, PS3)

Weathered 10mm pistol missing mesh bug
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:

The 10mm will still do damage when used in V.A.T.S with this bug, but not outside of it.

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. [observed on PS3 and 360]
 * Confirmed on PC, as well.

Crashing 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 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 (seen with all 4xx series cards).


 * With trait selected with 20% slower firing speed gun at time "spasms" firing multiple times, possibly due to stacked fire commands. (Not seen here on 360, so far)


 * 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.


 * 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. This is fixed by putting the cards into any container, then retrieving them.  The cards then go straight into your deck. (Note: There is a workaround for this bug. If you place the cards in a container and then remove them from the container one at a time, they are then added to your caravan deck. Similarly, placing them in a companion's inventory and removing them also adds the cards to your deck.)
