Making a report because I am getting irritated trying to fix it.

I suspect that the level.getUncachedNoiseBiome() might just not be very accurate, but I don't know how else we'd safely query biome at worldgen time. And honestly I could be barking up completely the wrong tree

Seed for example:

Now that the ocean surface generator is fixed kaolin is not visible, the veins are still generating when they shouldn't, they are just hidden and only a few blocks actually get placed. Not a balance issue, just a jank issue. Also worth keeping a lookout for this happening in other biomes it isn't supposed to.
