When I try to join in a specific realm, I get stuck on "building terrain"

Steps to Reproduce:

1. Not a reliable way to reproduce.  Althought more people have witnessed it in the same realm.

Observed Results:
When attemting to join, You won't be able to pass the "building terrain" sceen, no matter the version, how many times you close and reopen the app, restart your device, and attempt to join from another device. Not even waiting for long enough will get you over the screen.

Expected Results:
That just shouldn't happen. You should be able to see the "Done" screen after a while!
