First off this is obviously a beta so features and processes are still being worked on (so thanks for helping us fix these issues!)
It appears the reason the game was takendown was due to it crashing on start up. Unfortunately I have no more details at present (what the setup is etc)
Going forward we want to make sure you guys have an opportunity to fix the game. Even more important will be the playtesting functionality which should eliminate a number of these issues up front before the game is sent to peer review or published
