Lost asylum? Never mind (Android) (Fallout Shelter)

So, people are complaining about the disappearing shelters even in the Fallout Shelter comments in Google Play. I came to this method myself, although maybe this is not the first such topic. And I don't know if you can fix all the shelters or only the "Chosen". So, let's get started.

1) Go to your device's home folder and open Android / data / com.bethsoft.falloutshelter / files.

2) Delete the file Vault [1, 2 or 3, depending on which slot the vault] .sav occupied.

3) We are looking for the Vault file [1, 2 or 3, depending on which slot the vault occupied] .sav.bkp, select "Rename" and remove the .bkp part from the file name.

Now, in theory, the broken shelter should "come to life". Good luck)
