Sometimes, when you're in the game room, the host will be unable to communicate with the clients. All clients can chat with each other, and the host can see the clients' chat, but the clients do not recieve messages sent by the host.
When the host starts the game, the clients do not start.
It basically seems that the clients do not recieve any information from the host.
I can't really give you more information than that, as it doesn't crash per se. It kind of has to be experienced.
