A couple other bugs I noticed:

A bot will sometimes fire a shot at an enemy, then turn around and walk away, like it thinks the enemy died, bit it didn't. This usually results in the demise of the bot.

Sometimes bots charge an enemy running full speed backwards.

Bots will fall off the same high place over and over and never seem to learn the danger.

It would be very helpful if a bot's path is blocked by a button-controlled entity (like an elevator or door) if the bot would use the button to unblock its path. There are a LOT of great maps out there that have an elevator or worse yet, a spawn area with a button-controlled door, both of which result in stuck bots. de_shuttle_n8 is a perfect example; the CT bots run down the elevator shaft and die cuz the elevator is at the bottom, and the T's are permanently stuck in the spawn room cuz the door opens with a button.
