That's not his problem. If you see he's clicking himself and his avatar moves, it happens with the same on the retro I'm working at, which I haven't had time to focus on that right now. Basically what his problem seems to be is when he clicks his own avatar, it moves to a certain place in the room, possibility in it's been coded inside the emulator which needs to be found and fixed.You have to configure it in your room settings I think -> Allow to walk through other users, its a room configuration.
