A short while ago, I think it was just after the 1.2.1 update, there were some odd things going on with the lobby; lots of games were getting abandoned, game statuses weren't getting updated, etc...
At one time C64 had about 3 games listed as open. One of those games seems to have 'merged' with a game I was running at the time.
http://www.planetmule.com/hi-score-game/game?game_id=15855 This page shows the stats for a game c64 hosted. Neither of us ever even joined each others games. If you look at the chat log, it's the chat log of my game - somehow connected to C64's game. I was hoping this would get fixed with the other fixes at the time.
There is an odd overlap, and it's listed as an abandoned game -which is wasn't, C64's game was abandonded.
