I'm trying to make a modpack that has the player starting in the Betweenlands and traveling through dimensions. You already added great ways to make tree portals to other dimensions which allows me to make this, but I need a few creatures to spawn that do not naturally.

In Abyssalcraft I have shoggoth that will spawn on shoggoth biomass in other dimensions but not in the Betweenlands. Something seems to be blocking the spawning. I have tested this in the Twilight Forest and in the overworld and both spawn as they should. If I put down the biomass block in the betweenlands, they do not spawn.

Is there some code that is blocking other mobs from spawning? Can it be removed with a config setting?

NVM, cuz I'm an idiot...when testing maybe taking the world off peaceful would work.
