Aside from the brief outbreak of floating people, I've had few technical issues with Fallout Shelter. However, this morning I suddenly found myself unable to get to the Objectives screen. I had been playing for about an hour, completing objectives without incident. I'd just finished "collect 10800 power," and when I pressed the Objectives button on the right menu bar, the game paused for a second, then crashed. Since then I've tried to reach the Objectives screen a dozen times, either from the menu bar or the progress pop-up, and every time it has crashed.
Also, and this is a suggestion, not a bug, but I'd really like to see the progress pop-up placed somewhere other than over the Rush button. Thanks!
