The following I noticed before the crash. Animation became jerky, zooming went out of control when fires, raids, and rad roach attacks took control of what you were doing. Game would just quit often. Then wouldn't launch at all. I contacted Apple, no refund. Period. I have attempted to contact Bethesda, no response yet.
I had more than 68 dwellers, but a lot of rooms, maybe too many. Apple legal and Bethesda legal conflict with each other. I love Fallout, but this game needs more work in the advanced stages, final stages...
