Fallout Shelter bugs

This page describes and lists any known fixes for known issues and bugs on the iOS and Android game Fallout Shelter.

Guidelines
Please place any bugs found here with appropriate details on how they occur, and if any known fixes are available.

Android

 * Objectives cannot be removed each day on Android Lollipop version.
 * Resource bars do not decrease, resources can be gained and will be added but the bars will never decrease. This happens when you try to do the glitch time going forward your phone time settings and back again. There is no fix at the moment.
 * The first tutorial that has you building the power plant. After that it tells you to select a dweller to assign to the power plant and the dweller cannot be selected.
 * 3rd Expansion of rooms not joining together - when the player deletes a room to create space for a room expansion, room expansion won't register and a single room will be built.
 * All dwellers have blacked out faces.
 * Sent out an explorer for less than an hour, he now has 20 items, and is going to take several thousand hours to return.
 * During raider attack if the game crashes, upon reloading the vault is still in "under attack" mode but there is nothing to attack, raiders are already gone. Resources no longer produce, nothing progresses. The room that was being raided still has dwellers with HP bars ready to fight, but nothing to fight. All other rooms look like they are operating normally but do not produce any resources.
 * When in loading screen after choosing vault number, the game will crash and sends back to phone home screen.
 * Occasionally when sending dwellers exploring, they will be able to explore forever without any events or without gathering anything.
 * Constant crashes when opening objectives screen. Game restart does not fix the problem.
 * Game crashes on "Please stand by" screen if the cellphone shut down while playing previously.
 * The only known fix currently is to completely reinstall Fallout Shelter, as the crash destroys any existing saves.
 * When assigning Vault Dwellers to a new room or when two couples go to have a baby at the same time (overlapping themselves), occasionally they will become invisible and unable to be selected. To fix this close down the app completely.
 * Radroaches become invincible killing all Vault Dwellers in active room, Suggested fix is to move Vault Dwellers to a new room and wait for rad roaches to move into new room. Closing the application and rebooting phone does not fix this bug
 * If your phone's batteries run out after opening a lunchbox and unlocking the cards, the cards will disappear once your game has restarted.
 * When exploring the wastes, sometimes your dwellers will report finding caches or refrigerators, but when they open them, no bonus item is granted.
 * Undraggable Pregnant - When attempting to move a newly pregnant dweller back to her job she sometimes becomes selectable but undraggable. It seems only a restart fixes this.
 * In radroach incidents, sometimes the workers will animate as running around uselessly or continuing their work task instead of assisting with exterminating the radroaches if they are unarmed. (Note: This is possibly a feature though, rather than a bug)
 * XP earned while your vault dwellers are exploring the wastes doesn't seem to increase their level.
 * Stimpaks can not be applied to dwellers.
 * Invisible Corpse - When reviving dwellers there's a chance that an invisible corpse will remain and upset anyone working there. The only known ways to fix this so far is to delete the room and rebuild it or have some other dweller die in the same room and deal with the corpse.
 * Attacked / dead dwellers - it seems that there is a bug during raider attacks when dwellers from other rooms taking damage although raiders are not there. The dwellers in the room where raiders are do not shoot.
 * Near invincible mole rats that won't die until everyone on the floor they appeared on has died.
 * When opening the mission tab game closes without notification.fire wont go out dwellers dont take damage from it cant collect from other rooms while its happening
 * When Explorer returnees and you collect the items you dont get all the items. even with 2 fully upgraded storage rooms.

iOS

 * Losing Items from wasteland - When a dweller returns from the wasteland select the Item in the detail screen and hit the collect button.
 * Random crashing - Variable rate by device, game will freeze up and black screen with no discernable pattern; App will not close and can be reopened once the device returns to the home screen. Brief data can be lost in these instances, such as caps gained, objectives removed or completed, and Rooms built. Can also result in the Permanent Pregnancy bug.
 * Permanent crashes - If your Vault is bigger than 20+ civilians, you could maybe never load your Vault again because of permanent crashes at the loading screen of your Vault.
 * Permanent Pregnancy - If the game crashes while naming or after hitting done when naming a baby dweller, The mother may remain pregnant and not leave the pregnant state after rebooting. Another possible cause appears to be deleting or modifying the residence in which the dweller got pregnant, after they've gotten pregnant, although this is not true in all cases.
 * Radroach Armageddon - During a RadRoach infestation, it is possible for the RadRoaches to never die and eventually kill all of your dwellers.
 * Rush Crash - It is possible for Fallout Shelter to crash when a rush is attempted (in any room, on any device).
 * Event Item Deletion - If a dweller is equipped with rad and stim packs and is on his/her way to the wasteland but the expedition is canceled by an event such as rad roach infestation, fire or raider attack, the items equipped to the dweller can be lost.
 * Invisible Corpse - When reviving dwellers there's a chance that an invisible corpse will remain and upset anyone working there. The only known way to fix this so far is to delete the room and rebuild it.
 * Undraggable Pregnant - When attempting to move a newly pregnant dweller back to her job she sometimes becomes selectable but undraggable. A restart will fixes this, also dragging other dweller in the living room untill the pregnant one is kicked out.
 * Clothing bug - After shelter a random survivor his original outfit is going to continue in his body instead of changing to a vault jumpsuit. This can be verified when going to change her or his outfit appears the name of the clothing with an number in the end, example: Casual01.
 * Post Incident Sound bug - Even after the attack to end the game audio continues with the alarm ringing and the sound of roaches and shots (if every dweller where armed) even life in the vault being completely normal.
 * Objective Reset - Objectives will sometimes reset back to zero, usually overnight. This happens frequently with the longer ones, such as "Explore the Wasteland for 14 hours," "Collect 2300 Power," or "Deliver 16 babies."
 * Dwellers not appearing in collection - When you get rare or legendary dwellers, they don,t appear at the collection, though it works properly with weapons and clothes. It can't be solved by restarting and will stay like that for all your shelter life, even if you get all possible dweller cards.
 * Dwellers change outfit in wasteland randomly - Dwellers sent to explore the Wasteland will sometimes change their outfit, seemingly random. Problem is the original outfit will no longer be available.
 * Dwellers can become invisible - Unknown cause but closing the game and reloading it bring them back.
 * Outfits in the Survival Guide - outfits can appear in the Survival Guide as having been found when they haven't yet been found (eg some legendary outfits, though they are not wearable), and outfits can appear as newly-found when they have been in the Survival Guide for some time. This bug has coincided with an outfit being wrongly listed in the text for a dweller on exploration (eg Commander Fatigues - showed in text as such, but wasn't in her collection list). Bug encountered when about 60 different outfits had been identified in the SG.
 * Dwellers walk diagonally through walls and ceilings.
