Important glitch with the Realms system.

This has been happening to quite a few users and I speak on their behalf. 

We have a randomized joining glitch on Realms. For example, I have permissions to enter my friends realms but every time I click join on any of them I end up on one realm that isn't what I'm trying to join. Another friend of mine had a similar issue but he ends up joining a random realm, some he isn't even invited to. One last issue is sometimes a user ends up in a flat grass biome when joining their own realm.

Please fix this quickly, Java Edition user "Punadian"
