Steps to Reproduce

have the above version of twilight forest.
have mobstacker 1.20.x forge 1.0.11
Go to twilight forest and find ore hill.
swarm spiders will spawn then combine. Spiders will duplicate as stacked spiders. Spiders will sometimes spawn into walls and spawn additional spiders, sometimes in walls also.
Spiders will combine with new spawned spiders and keep doing so creating infinite spiders. spiders die in walls dropping loot.
Infinite loot piles up.

What You Expected

Them to try avoiding spawning in walls. For them not to spawn stacked copies hopefully that can be fixed.

What Happened Instead

Spiders spawn and stack together into one. they fight me and take damage spawning more, sometimes in walls leading to more spiders spawning and stacking together. They quickly reached the max stack size, which was then only 16, and then began duplicating as stacked spiders.
