Issue Description

This probably isn't a bug but I'll like to point out that GoG's end mobs doesn't spawn in nullscape's biomes in 1.19.2 yet in the 4.0.0 (1.20.1) version they can spawn there without any problems.

Additional Information

No response

I don't see a reason for this to be the case as the biome tags used in 1.19 and 1.20 are the same
