No it hasnt happened to me, also yesterday when i was in host_hulas room some girl said she kept getting disconnected and that it was dc monster and host_hula said no there isnt a dc monster in vmk anymore we sorted it lol, so i dont know!!!
Dissconnecting is not completely gone from VMK, it happens rarely though. Crashing isn't new to VMK though, it's been here since dissconnecting for all I know. I normally only crash after way to many four on four games in pirates or mansion. I use to crash every time I entered the music mix lobby, no though, I do not.
