--- Comment #1 from Erich Hoover ehoover@mines.edu 2009-12-12 01:40:29 --- This demo is a large download and it's pretty late here, so I'm going to have to look into this issue in the morning. I would, however, like to double check that this happens with the single player demo (the link you attached) as this patch only touches network-related code.
