Observed behaviour

When using Ancient Spellcraft and Special Mobs mods together, Special Mobs variant entities cannot be spawned, summoned, or otherwise appear in game - acting as if they have been unregistered. Attempting to summon or spawn these entities results in a fatal java error, as per latest version ATOW 1.12.2-1.7.5 rel. 6/9/2024.

Below is the error in question, using Zombie Brute spawn egg in a freshly created world on a test profile containing only the mods and their related dependencies. Further testing concludes this as a specific incompatibility between Special Mobs and this mod, and not its parent mod Wizardry or related dependencies.

Expected behaviour

SpecialMobs mod variants should be properly registered and constructed; with this mod installed, for a reason I cannot divine, they fail to do so.

Steps to reproduce

1. Create a test profile with only Special Mobs, Ancient Spellcraft, and their dependencies.
2. Create a new world.
3. Attempt to summon or use a spawn egg for any Special Mobs entities.
4. Spawn Eggs: No behavior observed (Nothing spawns). Commands: Failed to summon entity error.
