my rank dropped 150 to 200 in one game, I checked and it went down 7 times in the same game

It seems to be happening a lot. The site is not fully registering when a game is complete and the winner needs to keep ending their turn multiple times for the game to finish. Each time it registers as another "win" (or loss).

tom has a process where he recalculates all the scores and it cleans stuff like this up, but it takes time to run.  I am sure he will do so after he figures out what the performance issues are with the site.
