Sometimes cave biomes will generate above the ground in mountain biomes. In dripstone caves, the dripstone itself doesn't generate but the biome does. This causes a splotch of stone in the middle of the mountain instead of snow.
An example of this bug:
Version: 22w15a
Seed: 106642798
Teleport command: /tp @p 84043 130 -100767
How to reproduce:
Find a mountain biome that has a dripstone cave underneath it. Note that this issue only happens on some occassions.
This may be a minor issue but it can cause ugly splotches of stone in the middle of snowy mountain biomes. It has the same effect as a microbiome. I've also uploaded 2 pictures of the example i gave above. In the first picture you can see that it is infact a dripstone caves and not a stony peaks. And in the second picture you can see a good overview.
Thank you for taking your time reading through this bugreport. Kind regards keller1971.
