So I'm using the synitra connector mod to play with the fabric better nether mod and the nether tarantula hawk doesn't spawn in the nether like it should. At first I thought that the problem was due to the way in which biome tags were handled by each modloader and that they were incompatible, but then I tried modifying the files in data/alexsmobs/tags/worldgen/biome and I realized that If I assign biome tags to other mobs like the soul guster it works fine. Even the nether variant of the enderiophage works, so the problem is only with the tarantula hawk. I also tried assigning a Minecraft vanilla biome tag and it didn't work either. I wanted to know if this has a way to be fixed or its coded that way and there is nothing to do.

After trying again for a few minutes I solved it, seems that I made a mess with the nether tarantula hawnk biome signing
