Running as a dedicated server is recommended when you guys want to play for a number of reasons, and they will auto load fine in that mode.
BUT, if you prefer to run in listen mode, there IS already a menu option to add a random bot in the fritzbot menu system. Denny added it last version. Just have the f0x bind a key to the random addbot cmd, and he can add as many as he likes, and the code will intelligently add the right amount of each class to make the game playable. Just hit the "ESC" key, goto the the "controls" and look in the "fritzbot" menu area.
Also, execing a cfg file is always possible. You also could just make your own special config (call it "bots.cfg" and place it in your fritz dir, and just exec it when needed).
If noones had any AI issues, I'll make an announcement.
Cheers!
