Actually... IT could be something more ominous.....

Somewhere else in this forum you'll see a post of mine that on a dedicated server, bots were not automatically joining, even though RB was in the META LIST.

I have since discovered the reason for this.... If the last line in your autoexec.cfg is a 'map <mapname>' command (without the quotes) , then the bot.cfg file is not parsed. I am not sure if this is metamod / amx / rb / steam that this is a side effect of. As soon as I removed the 'map <mapname>' command from the autoexec.cfg file, the bot.cfg file was parsed and bots joined automatically as before (how stupid of me not to pick this up earlier).

Anyways, BEFORE I tried removing the ''map <mapname>' from the autoexcec.cfg file, I tried something else that worked as well (which I did not do before). Copy the bot.cfg file into your cstrike folder (same folder that liblist.gam is in), and then for a dedicated server, add 'exec bot.cfg' (without the quotes) as the last line in the server.cfg file. For a listen server, it is not required for some reason.

Maybe a workaround for bots not joining after map change is to add the 'exec bot.cfg' command (without the quotes) to the end of the server.cfg file, as this file gets executed after every map change.

I agree with Stefan about RB working with map changes. For your info, I use the following setup -
