Made a sawmill and it doesnt strip and cut biomes you'll go wood, according to jei, they have stripped versions of their wood, but no recipes on obtaining it, im assuming once recipe has been implemented it will work? Not sure, if this should be on Biomes Page feel free to remove, just letting you know it doesn't currently work in 1.16.5

This just needs a datapack to add support. I'm working on one for my personal pack, and I may put it in a repo for others to use.

Repo Here

(I forgot about this issue until a few minutes ago).

I recommend OpenLoader for loading these without having to put them into each world.
