We have the same issue, whenever I get the T-Pose Bug or other non playable Bug as a client, the host has to go into the camp, save and reinvite me after I killed the game with the Task Manager. I read somewhere that the host is loading some files faster than the client, makes sense if you are in the city of Baldur's Gate. In the camp there are less files to load. Back in the Game you can port everywhere.
I still hope they fix this, happend to me 3-4 times in a session and you loose quiet some time and time is precious.
