I have been working on this vault for 2,5 months and is currently at 193 dwellers. Spent quite a bit of cash on lunchboxes and Mr Handys.

I logged off normally this morning (exiting though Main Menu and then double tap Home button and close app)

Now I can load my Vault but when it tries to save it freezes for a second and then the app crashes. Next time I start it it will load the save from this morning but the same thing happens again.

I downloaded iBackUpBot and got the log file:

Anyway to fix this? I dont care that much about the money but I'ld hate to lose the Vault after spending so much time on it. Have another much small Vault and it seems to work perfectly
