Well I like many others have had a problem with the save files for the game being corrupted when exiting the game.

Initially the game would crash just after the Bethesda spash screen. I backed up all the files found under Android\data\com.gamesas.falloutshelter and then uninstalled and re-installed the game. All the files under the cache folder loaded with no crashes. However when re-loading the save files, Vault 1.sav caused the game to crash when accessing the vault list. When only the second save file (Vault 2.sav) is present the game loads normally and the vault is acessable through the Vault List. Re-naming the save files had no effect.
