Even when all players agree to a Draw, there is still a rating change for TMM? I've experienced the same thing, and was surprised.
How can you determine a winner/loser if it was a Draw?
But then I checked the games a day later, and they correctly say 'DRAW' and no rating change.
So it all worked out in the end, but that is a bit a confusing!
Fichom - Have you rechecked the game results a day or two later? They may correctly appear as a Draw.
