I guess I should have said what version I was using as well. Whoops :/

Thanks for your quick work. I enjoy playing your packs.
So I have a bug to point out.
For some reason, random clusters of vanilla ores are spawning at the max build limit above ocean biomes.
I'm pretty sure this isn't supposed to happen and I have no idea what's causing it.
