Overview

Datapacks changing world height (such as jjthunder overhauled) is incompatible with terra blender, it just sets vanilla height values

Why would this feature be useful?

This mod could be very useful for worldgen, but such a problem has the most influence in generation

at least for noise generation.

I second this. Biomes created via datapacks currently cannot be loaded if one has mods installed

This should be fixed in 1.18.2.
