Yes. And many other problems. As you might have seen at my server that is up right now, there are many problems with playertypes.
When you open and close the inventory, the following problems occured:
The Prisoner's heads that are black then go to the right avatar,
The playertype changes back in a minigame,
when not in a minigame, jet goes away.
Why are these things happening? Is it an add-on?
