Cave biome

[grimhurtz]

I noticed that I only found malachite near deepcave. Is there any chance of bloodstone appearing near a specific biome?

Your sample size is very likely way too low to draw any conclusion but there is definetely some fuckery going on...
It wouldn't surprise me if your theory end up being correct though.

Cave biomes are much smaller than ore biomes. Just random chance.
