    Introduces an Oak counterpart to the Old Growth biome collection

    Old Growth Forest simply adds an uncommon Forest variant with large trees. This biome has a chance to replace regular Forests at high enough "Weirdness" values, which is the same generation criteria for Old Growth Birch Forests, Old Growth Pine Taigas and Old Growth Spruce Taigas. Please note: Project is currently in Alpha.

    I have no idea if you will see this. Been trying to figure out how to add new biomes to the existing overworld for my own datapack and with the changes in 1.21.11 it's been a real challange. How did you get this to work? And is the tags file at all important to the placing of the biome itself?

    Not OP, but i do a lot of worldgen stuff as well, to answer your question, use the online editor called "snowcapped" its hard to get used to, but is basically mandatory if your planning on doing anything related to custom biomes. Additionally, the biome tags do not do anything regarding placement of biomes. Biomes are placed strictly by where there criteria is met during density function processing.
