Update -
V3B21d:
+FIXED problem reported by mhanor (bots with the skill lower than 100 shouldn't infinitively get their crosshair to the hell when the enemy is no longer visible). That should help a bit also with bots looking up and shooting into the sky.
It needs to be more tested to confirm if the problem is fixed or at least significantly reduced.
Anyone can test it (many hours) and tell me if this version works better then the previous one?
