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.

iOS

 * Loosing 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 cause of permant 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. It seems only a restart fixes this.
 * 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 - Occasionally, if an objective is incomplete for a day or two, it reset back to zero. This can happen to any objective, but happens most 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.
