I've noticed this too, so far the bots crash for me on de_dust and cs_india, usually changing to or from the map, there's probably others too but I've yet to spot them. I've only recently figured out it crashes on certain maps after 2 weeks of crashing.

I couldn't figure it out before and probably won't now but if your lucky you will get an error message to go off, I don't >
I'm glad someone else has the same problem, maybe we can figure something out.
