Some mountains generate with very little stone, as shown in the photos. This is on a default world type.
Example 1: (Jagged peaks)
Seed: 34752912104976
Coordinates: 43, 192, -20
Example 2: (Stony peaks)
Seed: 868565863016403259
Coordinates: -89, 117, 181
Example 3: (Jagged peaks + Stony peaks)
Seed: -4680646807128482073
Coordinates: -6645, 153, 24228
Example 4: (Jagged peaks)
Seed: 1124678029
Coordinates: -185, 207, -10
Example 5: (Jagged peaks)
Seed: 1050958664
Coordinates: -27, 207, 10
Steps to Reproduce:
1. Load up a new world
2. Find a mountain biome (Preferably jagged peaks but also stony peaks)
Observed Results:
After a few tries a mountain generating incorrectly (Like in the pictures provided) may be seen. The mountain has almost all of its blocks missing. I've tried it with many mountains and this bug seems to affect 1 in 5 jagged/stony peak mountains.
Expected Results:
The mountain should generate normally.
