Hello, my brother is having an issue with the real world mission where the doors close too soon and you can not get through, we have the latest version of the game (I think, we play over LAN offline, have been for a while) but I think it is because he has a bad machine although I believed it was fixed. Also, I am only able to join his games but he can not join mine, he gets a "waiting for host to accept connection" message but shortly after it says the session is no longer available.
