My roommate hosts a game, a few of us join. He can enter caves, others can enter caves, I cannot.
I'm guessing it's a loopback issue with a client and server inside the same router?
Either way, I get disconnected from the game, when I try to enter a cave.
attached server log and client log
1) Have buddy on Lan host game. 2) both of you join game 3) he tests cave 4) I jump in cave, says connecting, then it says the "Try yelling louder" error message
