What did I just see?

[parker_soups]

I was in a game, one of the "I can dupe 4 u" on closed non-ladder. It was the ol' 2-person dupe scam. ANyway, the guy claiming to dupe was a Sorc and s/he said, "watch my new trick" and the guy disappeared in act 1.

Nothing on the screen showed him leaving. He just disappeared. I am guessing the he teleported out of town, but couldn't find him. Anyone have any ideas on this?<!-- / message --><!-- sig -->
