The new UI is very cool, but there are some issues with it. I've heard several things from other people, but I noticed this one as well...the wins-losses not being the same for teammates. Check out team G here (under Players tab):

Awesomeguy got booted, but the game is still going on. Should it count as a loss when booted/eliminated before the game is completed?

Hmm, seems odd the way it is. Although this is the way it works in Open games, were being eliminated/booted counts as a loss. The loss is "updated" into a win when the game finishes (and the now 1-man team wins, otherwise it remains the same.)

That's also how it shows up if you go to Common Games with a player.
