Fallout 4 Bugs

Crashing, freezing and other hardware- or software-related issues

 * Game random crashing/freeze often enough on certain pc configurations to make game play frustrating. Using Beta version seems to have resolved this. See instructions here http://gearnuke.com/fallout-4-download-1-1-30-beta-update-fix-pc-crashes-related-xaudio-drivers/#
 * When talking under water the game crashes.
 * When using multiple monitors with Nvidia SLI, the lower half of the view will have a dark band.
 * Custom resolutions for multiple monitor setups require editing Falloutpref.ini file.
 * Disabling "Windowed" mode in settings with NVidia SLI enabled and using multiple monitors will cause crash on loading screen.
 * There is no Beta version (or tab), for some users on steam, if that counts as a software-related Issue.
 * Those who does not have Nvidia or AMD, the game crashes to desktop several seconds after clicking new game, this disregard is a very common problem.
 * If running the game at a framerate over 100fps, after exiting terminals, there's a chance that the player will be stuck and will only be able to turn their head. The higher the framerate, the more common this bug will occur.
 * When using armor with the Chameleon Legendary modifier, the PipBoy will frequently refuse to work. If crouching and invisible, attempting to access the PipBoy will sometimes result in the UI being rendered partially or completely unusable. If standing and invisible, attempting to access the PipBoy can result in the PipBoy being transparent so the user is left looking through the character's arm.
 * When accessing a terminal on a desk, the camera will sometimes move forward too much and cause the player to clip through the terminal and stare at the inside of the machine. Exiting the terminal will resolve this.

Menu-, HUD-, inventory-, and radio-related bugs

 * Settlement UI for food resources can glitch out displaying duplicate food icons for plantable food and some plantable food icons may disappear but is still selectable.
 * Occasionally the Pip-Boy texture will fail to load, rendering the in-game menu invisible, but tooltips and keyboard controls continue to work. This can be fixed by reloading from a quicksave.
 * If the Pip-Boy becomes invisible after you exit power armor, you can fix this by exiting the power armor, going to a workbench, transferring over whatever clothes your character is currently wearing, then get back into the power armor and exit it again. Your Pip-Boy should now start working again and you can re-equip your clothes from the workstation.
 * Pip-Boy becomes invisible after experiencing "doubling up of powered armor" bug. Solution: https://www.youtube.com/watch?v=lMYFBRKjiYI
 * In first-person view the player character's weapon may disappear from the screen, even though the weapon isn't holstered. Holstering/unholstering doesn't fix this but switching to third-person and back does. -Same thing happened to me but switching weapons fixed it.

Physics engine glitches

 * When talking to a companion in a moving elevator it is possible for player character to fall through the floor and die.
 * The dog companion of the Sole Survivor is able to push any non-solid object out of the way when dashing to follow its master, including cars, which cannot be moved by the player even when wearing power armor.

Graphics glitches

 * When using unsupported resolutions, such as a 5:4 monitor with 1280x1024 resolution, the lockpicking interface will be invisible.
 * When using ultra wide resolutions, such as a 21:9 monitor with 3440x1440 resolution many of the games menus and hud rendering elements will be either streched or chopped off, of note is the power armor UI which will only cover 60% of the screen.

Effect bugs

 * Targeting Hud mod and Berry Mentats that have the effect to highlight creatures may turn some NPCs, such as Paladin Brandis and the robots at General Atomics Galleria, hostile.
 * The shader effect associated with cloaking can become permanently stuck in active mode, leaving everything with a green tint. (This cannot be fixed with the ResetShaders command, because ResetShaders crashes the game) ✅ To fix type in command console : rimod 00094636 for the night-vision glitch and/or rimod 002041B6 for recon scope vision glitch.

Non-player character-specific bugs

 * After completing some quests for the brotherhood of steel, when you re-enter cambridge police station, the floor will not spawn. causing you to fall through the world.
 * On PC latest patch, equipping Settlement NPC's with armor then equipping them with the exact same armor that they are already wearing will cause an instant crash to desktop.
 * Companions may encounter issues where they will follow, but not run or fast travel. If they are too far from the player when entering a door, they will not follow through the door. The player can initiate speech but will not be able to enter companions inventory.
 * Arturo may never man his stall in Diamond City, remaining in his house and sleeping often.
 * NPC's will sometimes walk away from the player mid conversation even mid sentence. this will cause the conversation to end. - Confirmed. To reproduce easily, quick save mid conversation, and when you reload the NPC may begin their idle wandering mid audio clip.
 * Companions may begin to emit a sound loop as if they were using the sewing machine from the armor workbench. Save/load might solve the problem for around 20 seconds, then it returns. Example: https://www.youtube.com/watch?v=GBAjdsh3b34. To fix it for now, command the companion to use an armor workbench and the sound should vanish.
 * After a raider or wild animal attack certain settlers will get stuck in the "thank you" mode. Constantly thanking you when you try to talk to them, locking out all other options such as trading and shops.
 * Sometimes settlers will get stuck in the "trade" mode. Constantly opening a trade window when you try to talk to them, locking out all other options.
 * Sometimes this bug will trigger when simply walking near the relevant NPC or shopkeeper. If the trade window opens while the player is already in another menu, such as a crafting window, both will be open at once. Attempting to exit the window will crash the game to the desktop. If you are experiencing the trade mode bug, exercise caution and save often.
 * Can also affect Companions who have been set as Shop Keepers when returning to the relevant settlement, even when this companion is active.
 * Companion (Strong) can become unable to move, and just kneel at the door where you enter a building spewing comments about the smell or whatever. Fast travel can fix this.
 * All NPC's in a settlement (including inactive companions, Brahmin, traders) will occasionally become stuck in an idle standing position, not moving through the map or attending to their tasks. Ringing the bell seems to fix this.
 * Caravan Brahmin with large cargo will occasionally spawn inside houses, and are too large to fit through the doorway to exit, blocking the path through the door.
 * While traveling with Hancock he may become invisible. Luckily his clothes are still present. This is temporary, and highly amusing.

Quest-specific bugs
Please place quest specific bugs on their respective pages. (Fallout 4 quests)
 * This bug may apply to other platforms as well, only confirmed on PS4 for me. After completing some brotherhood of steel quests, when re-entering the cambridge police station, the floor will not spawn, causing the character to fall through the world.
 * Shaun requests a random piece of junk to be brought because he would like to build something. If having sided with The Institute, Shaun will not take the item after asking.
 * Defending a settlement can fail to resolve even when the enemies are defeated. This makes it impossible to leave the settlement you just defended without all of your settlers dying.
 * Companion Preston Garvey will follow you around the whole game if you start, but don't finish, Quest [Taking Independence: Destroy Egg Clutches]. However you will be unable to speak or interact with him.  This essentially gives you 2 companions.
 * During the quest Human Error, the Deezer's Lemonade, might not spawn.

Location-specific bugs
Please place location specific bugs on their respective page (Fallout 4 locations)

Gameplay bugs
aiming down a guns sight (or using VATS).
 * While in 3rd Person any small movement either with the left stick of a controller or with walk enabled on PC will cause any camera/crosshair movement to freeze for a moment.
 * High FPS (110<) can cause character to become un-movable requiring a save reload after exiting a terminal. This bug may still occur with framerates under 110, but much less frequently. Some terminals are more inclined to produce this bug than others.
 * Might be caused by exiting a terminal quickly.
 * Happens less often if you cap the FPS with a video card utility. Start at 105FPS and try lower values if this persists.  One way to do this is using nVidia Inspector, editing the xml file for custom FPS cap settings.
 * When subtitles are on, conversations can become 'stuck' on screen with part of the conversation subtitle remaining while the conversation continues. Text is removed from screen when conversation is complete.
 * Sometimes text options do not show up in dialogue and NPC comments that the player character has not responded. A response can be selected by pressing the correct button but the text doesn't appear.
 * Saving the game near a mine, stepping on that mine causing an explosion and then loading the saved game the mine will disappear.
 * If player character changes their name inside Vault 111 before taking the lift to the surface, the player character can not walk off platform or enter Pip-Boy. Looking, jumping, and shooting functions still work.
 * Unable to draw weapon, use grenades, or pull up VATS after fast traveling. Fixed by zooming out into 3rd person view then back into 1st person view.
 * When leaving Sanctuary Hills, Oberland station or Sunshine Tidings co-op settlement resources will decrease until the player character comes back to the area. This can be avoided by leaving on foot, instead of fast traveling.
 * Sometimes when speaking with sleeping dveler, he/she awakes and stand on bed - then it is possibility that he/she ends on roof of shack where bed is located, unable to walk anywhere.
 * The player character can randomly teleport a short distance when
 * Assigning Settlers to a Shop can cause the whole settlement to reset forcing you to reassign everything, because your food remains green settlers will not self assign.
 * Loading a save at the same time as your character would become crippled (for example by an explosion) will result in the player character also being crippled. If reloading the save again, they are no longer crippled.
 * The player character stops moving in 3rd person camera after walking or running.
 * Random issue with being unable to reload weapons. Switching to a different weapon and back automatically reloads the weapon. Fix: Fire a bolt action weapon (such as a bolt-action pipe pistol or a hunting rifle) and reload the weapon. All weapons should be able to reload after that.
 * When putting down items in Workshop if the item flips around too much it will become blurry and can also cause your whole field of vision to become blurry, to fix delete the item and try to put it down again without flipping it around.
 * The Data>Settlements Tab of the Pip-Boy shows that settlements have missing resources (food, beds, power, water, or defense) but the Workshop menu shows true values. Settlers reflect the incorrect values and lose happiness until player returns to the settlement.
 * Food resource structures will become un-clickable and useless, and settlers will not acknowledge the item as a food source. Seems to only happen if placed too close to a another structure.
 * Items may levitate off the ground and become unplaceable in the settlement workbench
 * After the cryo-chamber opens the player may be unable to move. This is not fixed by reloading any prior save, and often new games will have the same issue.
 * Zooming in with scopes or using VATS will occasionally produce a teleport bug instantly teleporting the player somewhere in the vicinity. This may be correlated with higher framerates.
 * When reloading while moving in third-person, your character occasionally will continuously restart the reload animation until you stop moving or switch to first-person view. If this happens with a laser musket, the laser musket will continue to be cranked after each animation restart.

Companion App bugs

 * Local map is not shown at all.

Xbox One only bugs

 * The player character doesn't speak, his/her dialogue is skipped entirely. Happened during a conversation with Preston garvey, the animation turned to the player character but no animation or dialogue cam out of him.

PS4 Xbox bugs

 * Controls/input freeze when exiting cryo-chamber during introduction sequence. Can sometimes be fixed by hard resetting the console. Update on work-around for this problem on Xbox 1 Apparently if you try and start a new game while another one is still active on the xbox 1 this freezing will occur.  What I did was erased the entire game that the profile that was freezig (not the actual game itself, only all the data for his profile) Then restarted the xbox and started a new game with his account making sure no other ones were open.  Worked on the first try.
 * On Ps4 pressing O button while Workshop is open as if to look at pip-boy then exiting the Workshop will cause the O button to lock and not work, to fix reassign The O button in the Settings screen.
 * Doing the quest the battle of bunker hill makes everyone's hair blue.

PC only bugs

 * Tab key stops working when accessing the Steam overlay (Shift + Tab), you cannot access your Pipboy (or exit it). Accessing Steam overlay and exiting with Shift + Tab fixes this.
 * Going into the trade menu and clicking the "TAB)EXIT" button on the bottom can fix this.
 * Inability to access PipBoy may be caused by Steam Overlay on PC version. If one accesses the Steam Overlay using a combination that includes the tab key, but exits the overlay with a different key combination (such as hitting the Esc key), the tab key will become unresponsive in-game. This can be fixed by opening, and then closing, the Steam Overlay with the selected key bindings.
 * For some users when using VATS, Workshop, or upgrading the power armor, the outline glow of a highlighted object will be replaced with a static glitch that takes up the whole screen and displays the same color as the normal outline would show.
 * Volume shorts out at random times during gameplay.
 * Inability to shoot after exiting build menu too fast.
 * Invisible Body Protection.
 * Occasionally when Alt+Tab/Esced out of the game after returning menus will occupy a smaller area of the screen and the cursor will be off point, also affects iron sights (points to the right of center). Quitting to desktop and reloading fixes.
 * Mouse pointer fails to appear on main menu screen if a controller is plugged in, keyboard cannot be used, and disabling controller has no effect ("no" switches back to "yes" on the controller option in the menu). Can be remedied by unplugging the controller or changing bGamepadEnable=1 to 0 in Fallout4Prefs.ini. The menu option only will work and keep the controller settings if selected in-game and not if selected in the launch menu..
 * There's a slight chance the game will delete your quicksave making you load an earlier quicksave when quickloading. This might happen if you try to load too fast after saving or load too many times from the same save.
 * There is a chance when using a terminal, you can become stuck. The character will not be able to move, but can look around and jump. In order to avoid this glitch quicksave before using any terminal. There are some places that require terminals to open not accessible because of this glitch.
