Yeah, I was in Bastok when it was going on..I think it was about 10:35 in the morning (EST), and there were three of them, just standing in the fountain, changing avatars to crawlers, boms, and demons...^^ Supposedly they handed out cookies/crackers to the players that were there (it even came up as a purple SystemMessage), but if you didn't get one, the OCR team might be setting up a bazaar somewhere with them.
I couldn't stick around, since I had class...>.< It was cool of them to do this though...^^
