pb remove #bot_id
That's all I needed to know - thanks!

FYI: I did not see this written in the manual.
I figured the regeneration behaviour was a feature rather than a bug.
I suggest that you leave the regeneration behaviour in place to prevent a server from going empty, but add a cvar to turn the feature on and off (defaulted to on).
As for where to post a thread in here, this forum has subforums and a main forum, so I got confused. It may be a good idea to get rid of the main forum threads and move the existing ones to the correct subforums.
