Oooooh --- if you got that page, that means that's a Bug! If the page is in the PAGE LIST, then it's a page.
I just made a quick fix to the game authorization code, so it may have fixed it. But it probably didn't, since you were the author of the game ... and the bug was related to Admins editing games.
No less, could you do tell me exactly what page causes you that error? I will go and investigate.
