Overgrown Alpine Heights Mod adds compatibility between CliffTree and Terralith. Normally, loading both worldgen mods together causes one biome list to overwrite the other. This mod combines their climate tables into one shared setup. Both types of biomes now generate side by side across your Overworld at balanced sizes.
