As the title said, since this afternoon, in about 30s after loading my vault, the game crashed. I must highlight that I am able to load the game, but the game crashed thereafter.

I have less than 100 people (95), 600k+ caps, 3x3spaces nuka-cola factories (without water purification and garden), 3x3spaces storages,

3x3spaces nuclear, etc.

I tried building a new vault and it works like a charm, so there must be something happened in the advanced state of the game which causes the crash.

Im using IPAD mini 2.

Please do check the game as it is very irritating losing your progress after such long progress.
