I thought the same thing at first, that he had simply given up. But most times players just don't bother and let the game automove after 5 days or whatever.

We saw this with a non-league game and another player.

He's confirmed he never had a chance to make the moves in the league chat.

Could be a case of stolen password, but then why not all his games?

Plus the way it so quickly was ready with the next move, seemed automated to me.
