Description

Followers persisted from server A to server B.
I've joined server A where there are 7 followers (tamed wolves).
Exited server A.
Joined server B.
Now it shows server A's followers at 11787 blocks away. Distance is updating, but followers persist.
When I've unseated a wolf in server B, it added to the list. But the followers from server A are still present.
This only got away after I've restarted the game.
