I'm working on what the root cause of this recurring problem is.
I had one of the games that suffered from this problem (or some variation of it) but was able to finish turns and eventually eliminated the other player. However, the game didn't recognize it should have ended and is still going. So its not "stuck" but its always my turn with nothing but me and some neutrals.
I took another "turn" this morning just in case whatever you did would end the game once I took a turn but it made no difference. You can see other details in the "Can't end game" thread.
The game in question is: http://www.wargear.net/games/view/137078 (part of a tournament)
I have another one that stalled out in the Game termination process.
Just to follow up on my prior post. The game is now showing me as the winner and it is no longer my turn but it hasn't actually ended. The turn timer is running but its no one's turn of course. Consistent with the game not yet being registered as ended internally, the tournament the game is part of is not reflecting the result of the game and my tournament rating has not been updated.
Those games should now be fixed.
