coan.net: another one is playing around with weekend days and unsetting previously marked vacation days (if you set 20 vacation days and make a move on a 1 day game it will only timeout 20 days later. If you then unset the vacation days, the timeout is not changed - if the timeout date was set to only 1 day this wouldn't happen - currently if, when timing out, there is a vacation day set the timeout is already postponed 1 day)
I don't even know the game or the name of the player so I'm only guessing...
