Confirming that issue seems resolved with 1.2.1 update.
iPhone 6s+
iOS 9.0.2
1.2.1 update
My crashing vault is now able to be loaded. All my wasteland explorers were dead (1000 caps a pop to revive), but it appears to be fully functional.
Secondary issue with crashes when loading objectives screen also appears fixed.
If the team had been communicative about an incoming fix, I wouldn't have gotten my purchase refunded.
