I know you were messing with me some. Obviously I didn't think you wanted the ban hammer on me, 8). But I did have some network issues lately so it could have contributed to it. I was concerned the last few times we did some vs matches and I was hosting if it would be a stable connection or if my guests would have lag issues.
It happened last night when D was hosting. After it happened, he invited us back in and it worked. For some reason, it's only Calypso I think, and it only happens when we try loading that map while already in the room.
