Update -
V3B21a:
+Added the code to prevent bots looking up or down for no reason (need more testing to let me write here it's fixed).
+Added the new cvar - pb_firsthumanrestart (0 stops the function added in V3B21 - when the first human joins the server and there are some bots already playing there - the round is restarted). Now this function is off by default. You can switch it to on by changing the value from 0 to 1.
+Added code to let the bot reload the weapon at round end (if the bot doesn't see any enemy that time).
+Fixed - the vip bot shouldn't hunt the enemy anymore.
As usually, please, leave a feedback.
