Biomes O' Plenty End biomes not generating

[Hitaxas]

Seems this mod needs a preset for Biomes O' Plenty, as none of the End biomes for it seem to generate.

On MC 1.21.1, NeoForge 21.1.179.

Getting this too. Minecraft 1.20.1 on Java 25, Forge 47.4.13, with End's Phantasm 1.0.1 and Biomes O' Plenty 19.0.0.96.

I've done some testing and the Biomes O' Plenty biomes do generate, but only ever in tiny patches and missing all features (trees, foliage, etc). Oddly, even if you're standing in one, these patches cannot be detected by /locate, and when I tried adding a biome using a datapack, it was also not detectable with /locate (if it even generated at all). The features themselves aren't broken - you can use /place and they generate fine, so my assumption is that one of the feature-registering functions overwrote all other end feature generation which is what stripped them like this.
Can anyone playing with Nullscape confirm whether or not the biomes/features specific to that datapack generate? If they do, I might be able to find a workaround.
