when the error happens all members of the team are kicked and they can not rejoin the server unless there bodys are moved from the area it happened or they are killed.

Also that area then becomes a "No GO" zone for all players or they will be kicked with the error and unable to join back until moved or killed, to fix the area you need to restart the server 

from the error i posted it was the 3rd player when he joined the team it happened, then the error that shows on there name is the one given to all players when there kicked or try to rejoin 

I have released an update with a potentional fix for this problem. Can you confirm if this has resolved your issue?

Will test it and get back to you 👍

sorry for late reply, its all resolved in that update, Thanks 👍
