Good to see that this happened to someone else! Yesterday, I was playing a game of Groundwar, then when it finished, and I was in the lobby, the same thing happened to me; except that I had a " Carepackage " emblem, and not a prestige skull. You DON'T need a laggy connection for this to happen to you. I had full bars, and my Xbox 360 is connected directly to my router, with an Ethernet cord.
