I was playing matchmaking and I won the first game, lost the second.
I noticed someone else was in the queue also, he lost the round against the person I recently lost to and I ended losing the whole game.
I hope this was a glitch because I just lost because of someone else.
Happened to me to. It's just a bug in 5.0 that hasn't been fixed yet. 5.0 is only steam support right now, and its like a month old. Maybe 2; anyways, its not a huge deal, they'll probably fix it soon (the devs)
