magma cubes do not spawn in the nether in any biome. not naturally in the basalt deltas nor from naturally generated or placed spawners

Steps To Reproduce

1. Create a 1.21.4 world with the mod installed on fabric, no other mods except its dependencies
2. Go to nether and locate a basalt delta or magma cube spawner (or place a spawner and put a magma cube egg in it)
3. See that no magma cubes are there

Expected Behavior
Magma cubes should spawn

Logs

There were no logged errors but I will put this anyway I guess

latest.log

I hope this can be resolved as I am not sure of the repercussions of trying to remove the mod from my server

This is already fixed in future release 4.0.
I was stupid and wrote incorrect logic for Slime spawning… and completely broke both Slime and Magma Cube spawns.
