Two talks, one room?

Digital Vengeance and Xenoscan are both scheduled for Saturday 14:00 in Track 4 according to the speaker list. I assume one of those is supposed to be at 15:00 since there is no talk scheduled for that time/day/track.

This probably isn't the most efficient way to get the problem resolved.
