Aah! I think you have lead me on the right track here. I may know what happened...
There was one game where I picked up an open invite and made the first move. The guy in the other end didn't really want the game, but was merely trying to set up a game with his buddy.
He explained it to me (in a very polite manner I might add) and then offered me a draw as a mean to get out of it. Thinking there was no sense in the two of us taking a draw in a game that was never meant to be, I deleted it and wished him a good life.
Maybe something went wrong because I had the draw offer up when I deleted the game?
