Board Game Arena

A player left an untimed game of Tzol'kin (the log shows that this person went offline 30+ minutes ago). Before the player left, everyone was playing at a decent pace (as if it were a timed game). Because it is untimed, we can't kick them out once their timer expires. [NOTE: It is the last turn of Tzol'kin and, with nothing on the board, the player that left can't do anything to score any points.]
Is there a way to time the person out? Also, BGA won't let me play any other game or table when I have another game in progress. Am I forever stuck until this person decides to return to the game? Is there a way to play at a different table while waiting (esp. if the person never returns to the game)?

Hi

This is a training game: you can leave anytime, without penalties.
