Yeah I've only managed to get into 2 whole pantheon games so far, but the last one I just finished a bit ago is coming up as a 1 player game, custom, that I lost. Reality, strangely 7 players, a few drops mid game due to lovely lag, it was a Pantheon game, and we won. So the whole system for that seems screwy. The first entry was just fine. Then again, on the next page it also says i only played 1 game, so I have no idea. Achivements don't seem to be saving either.

You can get the same achievement multiple times.  Achievements do not currently appear on the site, but will in a future update.

We are currently on fixing the lost games bug.  What it does is it creates duplicates of your played games when somebody quits, and that duplicate defaults to some data that just happens to make it a loss.  We're working with GPG to get this fixed.

That likely means that a second game was created for the dropped ally and you were replaced with an AI.  When that second game finished, it took the AI's stats and added them as if you were the one playing.
