Well after playing on my server for a few more hours i've noted the following:

1. Bots seem to get confused by nodes that are close horizontally but separated vertically. After walking along a ledge in cs_winternights that goes around a corner, bots started getting stuck on the corner of the wall below the ledge. And the bots have a really terrible time navigating the stairs in cs_matrix, they constantly get stuck on the handrail in the landings.

2. The bots are smarter and meaner. Godlike skill is actually godlike now. I used to be able to waste hordes of "godlike" 1.0 bots without breaking a sweat, but not any more. If you ambush them from the same spot a few times in a row, then they will be gunning for you next round. It takes them a round or two longer than a human would, but they do catch on and adjust their tactics.

3. The bots don't go the same route every stinking round any more.
