Hello ;) Where did you get the mod from? Nexus or Thunderstore? I downloaded the latest version from Thunderstore when Mistlands was released and had no real problems configuring it to my liking.
And what do you mean with "starred mobs" (non-native english speaker here): Single creatures or groups of creatures? As far as i can see you can only edit the star chances for single creatures within the mod (which should not matter as groups of creatures (what i call "mobs") are clearly comprised of single creatures "grouped together".

Im not a pro at configuring mods, but i guess you need to do one of the following things in order to get rid of starred creatures. In the "org.bepinex.plugins.creaturelevelcontrol.cfg" file, you can either set "Minimum stars" and "Maximum stars" to "None" or, if you use "Difficulty = custom" (as i do), you need to set all (!) values at "Chances for stars at world level X (percent) =" to "0". In my config, there are seven world levels (0 to 6).

I hope this helps a bit (and apologies if im wrong ;) ).
