This mod makes all mobs spawn in the overworld, regardless of the dimension or biome it originally spawns in.
This includes mobs like Zombie Pigmen, Zombies and modded mobs such as Mutant Zombies.
This mod does not replace the original spawning system, but just makes it really messy with the new stuff.
This mod DOES spawn mobs that don't spawn normally, such as the Wither.
