the only time ive seen the bots not attack, but still freak out when seeing an enemy, was during the ns 3.2 change over... we fixed all that a long time ago though, so first make sure youre using this
http://skitch.dwmh.net/rcbot/rcbot_mm.dlldouble check your metamod.ini and make sure its pointing to the right dll, in fact, go to your server root, search for all instances of rcbot*.dll, and delete them all, then copy the one from dwmh.net to the server, that way youre positive that youre using that dll.
also, in \rcbot\bot_config.ini make sure the lines
config wait_for_orders 0
config dont_shoot 0
and
config max_path_revs 500
they should default to those, but you never know...
