      In the current Beta, caves don't generate properly above layer 0.

       

      Steps to Reproduce:

      1. Create a new world with experimental features enabled
      2. Run the following command as you move around the world: 
        /fill ~-1 -63 ~-1 ~1 ~ ~1 air
      1. Caves will only generate properly below layer 0 and less commonly above layer 0.
        1. The caves will also not generate through any custom blocks

      Expected Results:

      • The cave carver feature works including for custom blocks as per MCPE-78350

      Actual Results:

      • Caves don't generate
