lol normaly this plugin do that (in the script) but sometimes it work, fisrt time, tank spawn ok, no zombies and specials ok ...sometimes it work not !!!...
i think use this plugin alone in config cfg with certains other plugins !!! But cant use more vote past other config = bug !!!
P.S maybe manually : director_no_mobs 1 , director_no_specials 1 , director_no_bosses 1 , z_common_limit 0 ! but not really good
