When you enter your world and you are sleeping, it will immediately kick you out.

If you go into a world, and sleep, and while you are sleeping you get kicked out of Minecraft... when you go back into the world, it wont let you join. It will show the loading screen with "generating world" and then show the buttons "open chat" and "leave bed" for a few seconds, and then it shows the loading screen again with the text "Loading Resource Packs" and then it kicks you out of the app. This happens every time you try to go into that world. All other worlds work perfectly fine.
