Sometimes, if you quit a game early (or too early?), like when you see you were matched up in a 3v1 (with 2 AIs on your side), the game doesn't end as it should. I don't know if this happens because no actual concede is issued from you or if it's simply ignored, when issued too early in the game.

I had two incidents like that recently. One was where was on the all human team against a poor user who was matched up with 2 AIs on his team. He quit before the announcer even said "Fight!", but the game didn't end as it should. Another incident was today, when I was matched up against 3 human players with 2 AI players on my team. I immediately quit (but after the announcer said "Fight!", at least I think so), but the game didn't end. The problem is that those games will count as a loss for you, if the other team simply finishes stomping the AI: http://pantheon.demigodthegame.com/game/799615/player/27826/
