I tried out the mod with Oh the Biome's You'll Go and got bad chunk borders and odd mixing of biomes.
I know the mod just came out in beta so just a happy thumbs up for seeing it coming to 1.16 :)
I just removed and rolled back my backup.

Issue type:

• 🐛 Bug

Thanks for reporting!

Did you add this mod to an existing world?
If so, chunk borders are to be expected, as worldgen and seed usage will be altered.

yes I did. Is the add without worldgen changes issue patched? In that case would a person just need to bring in saplings as admin?

Ok, considering this a non-issue then.
