Realms is broken

Realms is having several failures, including loading, interacting, and gameplay.

Some issue scenarios include:

-Realms doesn't move past loading screen, stays forever.

-Realms loads, and says "kicked by owner" (I'm the owner)

-Realms loads, and you can play/interact for a few seconds, after which commands don't work, you can't see other players moving, but you can break and build (not saved), but if there's a mob you want to kill, you can't.

-Restoring backups or download world doesn't work, game crashes when you try to download and play a backup/world download.
