Features being hallucinated at wrong y-level with Oh the Biomes We've Gone

Follow up of: https://discord.com/channels/881614130614767666/1267132055385407700 I did some testing with just BWG and DH on its own and the same issues still happened, even with vanilla world height. I also checked by pregenerating chunks with Chunky and then enabling DH and the issue did not occur. So it does seem to be an issue with DHs inbuilt generator placing the features at the wrong position.
