Hey, thanks a lot. I must try it now.
Edit: I've just had a game of si_urban with bots (13bots + me). I mean, a full game. No crashes, no freezes, nothing wrong what-so-ever, except that the bots didn't go up the ladders on the rooves. I think the problem that makes the game freeze is either:
1) Waypoint flags
2) si_overtime waypoints has problems
I haven't tried laser or deep yet. I'll get to it someday.
Edit2: I've just tried si_deep. It freezes. The similarities between overtime and deep is that the bot gets stuck in the spawn room in both of them. Still got laser to try
