Issue Description

Massive performance FPS drops (prev. 200FPS, with mod 30 FPS).
Tested with new world.
I already tried to contain it with some mods, but after a while I gave up. It seems that it does not get on with another mod, because the Vampire mod runs great on its own.

Greetings from Germany/Dresden.

Reproduce Steps

Only use this mod with the mods down below.

I have tested again longer which mods behave here strangely. It is difficult to find the real cause with so many mods. But it seems that "TheAbyss+1.0.0gm+1.16.4" is somehow to blame. Both individually go wonderfully, but together the world is partially not even created.

Close the ticket, I'll just take out "The Abyss" and that's it. Sorry for the inconvenience.
