And yet another update -
V3B19c
+ FIXED yet another minor bug with ducking bots.
+ Changed - the bots are sometimes also ducking while shooting from other than awp weapon (similar to YapB)
+ Optimized again engine messages usage (thanks ghost_of_evilspy and his jk_botti)
+ Changed the way of checking if custom body parts (arms, legs, feet) are visible for the bot (to stop random part checks - another cause of shaking bots).
Please try it and give me some feedback.
