My Problem
Hello,
I've been experiencing crashes after I start loading chunks quickly (With Elytra). I have walked slowly to the location of the crashes to make sure it isn't corrupted and it's not. I've also noticed that it usually happens after I log out and log back in and if it helps my main base is inside the chunks that crashed my game.

How to reproduce
1) Log in to a world.

2)Fill chunks with a lot of data.

3)Unload the chunks.

4)Relog.

5)Grab an elytra.

6)Fly fast to the chunks.

Done.
