Hi,
my friend was about to play a match, he started changing joints when all of the sudden the joints when unselectable and waiting for player appeared on the middle of the screen, but the ghost image was still going. The chat seemed to stop though, by the chat it seemed like the opponent just left as it was starting. Is this what caused it? He re-joined the server and it started working again.

he may of had been still chatting.

But it let my friend move a few joints, then it seemed as if the player wasn't selected (all joitns white) and the ghost started going. Besides, the chat seemed to stop.
