Describe the bug
When a wolf spawns on any of the mod's biomes, it's just the regular variant, even though they have taggs assigned for different wolves variants, so I think it's a bug. As far as I tested (not with every single biome), this happened with all the biomes of the mod. Any of them spawned the correct wolf variant.

Crash Logs
None

How To Reproduce
Just do /locate with the tag of any wolf variant, find a biome of regions unexplored which is supposed to have that wolf variant, spawn a wolf and it will be the default one.
