Yesterday I tried joining this game: http://www.wargear.net/games/view/473373

Apparently I joined just a few seconds too late because I got the message that I successfully joined, but the screen showed warqueer as having joined rather than me. The game still shows up in my games list though even though I'm not a part of the game. I'm nervous that whenever the game ends it will affect my score and/or win record.

Is there some way I can be removed from this game with no consequences? Or will there already be no consequences to my score/win record?

Neat. Try clearing cache. 

...not quite sure why I didn't think of that. It did the trick though! Thanks =)
