***POTENTIAL SPOILERS***
I don't know if I am just overlooking something obvious (I do tend to be quite blind most of the time), but I am stuck at 10000 points at the convention. The only stamps that I don't have is the Receptionist and the Dressing room. When I go to the receptionist, all she does is tell me about the three action games, all of which I've already done. I can't seem to get the next 10000 points needed (I've played all the games multiple times, and talked to everyone again to see if they'd give me another stamp). Am I just missing something obvious, or do I need to continue on with the game to "unlock" the next possible points?
EDIT: I don't know what happened, but I kept talking to various people, and then suddenly an exclamation point appeared over the receptionist, where I finally got the remaining 10000 points, so I have no idea how it finally got triggered, but we're golden now.
