Can overrides pawn checks doesn't work with extra entries any more. Tried to change light levels and height as well no luck. Still uses inherited spawn rules.

Mind you I am right-clicking on spawners in creative mod to check if the spawners are working cos I gonna use it in RD.

The mod does not change spawn rules for mobs sadly :( it only adds new ones to the universal SpawnCheck. I explicitly do not check mobs spawned by spawners as that would possibly break all dungeon mods. Maybe I can look into making it an option though.
