After loading a world, the bed menu shows up and starts glitching. It crashes the app after a few seconds. All other worlds and even realms work perfectly fine, its just that one specific world. Creating a copy of the world and changing it to creative doesn't fix the issue. 

How I think it happened:

1) Got into the bed

2) Left the game by pressing home button instead of save and quit

3) Open the app again and click world

4) Glitch and crash happens soon after loading
