Ever since this event has been going on, my game literally crashes every few minutes. It slows down incredibly after about a minute of use and then crashes after just a few minutes. It's impossible to play for more than a few minutes without it crashing again. I play using an Apple iPad Mini and have tried shutting down my device and rebooting. That doesn't help. Neither does performing a hard shut down of the app and clearing out all my other open apps. Anyone else have this issue?
