Ok, I just tested some rounds on cs_assault. I didn't see CT bots get stuck in the vent, but maybe I didn't test long enough. Can you tell me where they got stuck?
1) In the entrance shaft? (This can happen when they jump on each other's heads...)
2) In the "lower" vent part (the one between the two access ladders)?
3) In the "upper" vent part (the one between the lower vent and the grate in the ceiling of the control room, directly in front of the hostages)?
Concerning T bots jumping/falling down the hallway, some questions as well:
1) Do the actually jump, or do they just walk/run over the edge?
2) Does it only happen when two or more bots run into each other and try to get unstuck, or does it happen with single bots as well?
3) In which area indicated in the attached picture (see below), do they fall down?
4) Which waypoint version are you using?

b) Time stamp: November, 1, 2004 - 93.7 kB
I can't test as thoroughly as you, so please try your best to point me to any glitches you can find, and I'll try my best to respond to your needs & problems and fix whatever I can fix.
Btw, glad that you like the bot!

I hope it will become even better...
