OMG I tried opening the app on my iPad Air 2 several times and the last time I tried both my vaults were missing. Had it on cloud backup but it's not there! I spent a lot of money on this game. What do I do? Both vaults I had were at full occupancy with pet and vaulttek packs bought. I am going to be so mad if I permanently lost these vaults. I just got an iPhone 6s but that shouldn't have affected it as Fallout Shelter wasn't even on the phone yet. I had it on our Wi-Fi but also the tablet has cell network available. Ugh!
