When playing on a modpack with Terralith I noticed there weer major errors with generating the blossom valley and marsh biomes. The former lacks any trees (it still has bamboo and cherry blossom leaf carpets) and has a mostly flat terrain while the latter generates crazy, extremely high terrain. Interestingly, the blossom woods seem to be fine. There are also no willow trees in the swamp biome, probably because Terralith generates its own swamp trees with the regular oak wood in place of the vanilla trees. I know that since this is a mod conflict and not a glitch in the mod itself, you may not care about it, but I think compatibility with Terralith would be really great, since this mod is very common in 1.18/1.19 modpacks and really improves the shape of the terrain.
