Sometimes things get a bit stuck, this looks like one of those cases. They system does have a lot of users on it though so a game can get a bit lengthy as it works through all the scripts.
If you want a more reliable/controllable experience, you should setup your own system. The SchemaVersus system may even be best as it lets you create pre-set maps and specify which users are involved in a round.

Anyways, sorry it's not performing overly well. I'll run some maintenance and see if that helps.
