The bugs with the game cause it to freeze when a player quits during trading or initial placement. For example: if someone quits during initial placement the AI doesn't pick up to place their piece. The only option is quitting. Does this count as a loss in the ranking system if you have to quit?
Can you tell me if the when the player leaves during set up if it was on their turn or someone elses?
Unfortunately I can't recall off hand. But the game freezes up often regardless, I'm sure you've heard about that already though.
