There appears to be a bug where it closes the app when evil mobs despawn. I've only noticed it on my newest tablet. As long as there are no evil mobs the app works fine. A spider mob, specifically, caused the crash when I noticed it was caused by hostile mobs. But if the Google Play services crash then it stops happening. This has made me quite confused now.

Originally, I thought it was a problem with the audio as every time I heard a spider it would happen soon after, but then on creative a single spider was left on the map and it crashed right when the spider left my range of view.
