MC-225781

The noise cave lava level and the cave carver lava level generate 1 block apart

Resolved

Fixed

Noise caves generate lava below -54, but cave carvers generate lava below -55. This causes weird lava generation when noise caves and cave carvers intersect.

To reproduce, use the latest Caves & Cliffs preview datapack, then use the seed 988896529693401708 and run the following command:

/execute in minecraft:overworld run tp @p -366 -54 -322
