It all started when a random encounter in game, didn't spawn enemies, but my dwellers still opened fire. The room had invisible enemies, which of course shouldn't have been the case. I realized it was a glitch and tried to reset the game by going to the main menu, but the load screen started blinking out and I had to restart my iPad to get it to stop. That's when the crashes started everytime I tried to reupload the save. It literally starts loading then freezes and backs out of the game.
Until this problem is fixed and I can get access to my old vault save, I have no intention in investing money in the game. I spent quite a lot money on that one save and I'm pretty upset/pissed off that I can no longer access it.
Using the current iPad and IOS.
