In previous versions of the game, the custom volumetric fog I designed for an addon's custom biomes worked perfectly, with no issues. Now after updating the beta, the biomes seem to load the wrong volumetric fogs.
Steps to Reproduce:
Create a new world in a beta previous to 1.17.0.50 with an addon that contains custom volumetric for for custom biomes, such as the one I have attached to the bug report.
Go to any of the custom biomes to observe the custom volumetric fog
Open the same world or generate a new one in the same way as previously mentioned, but in beta 1.17.0.50 onwards
Go to any of the custom biomes to observe the custom volumetric fog again
Observed Results:
In beta 1.17.0.50, the fog fails to load as intended and uses the wrong scattering, absorption and density values.
Expected Results:
The custom volumetric fog should load and display in the exact same way it had before, as this is how the functionality is intended to work.
The fogs in these biomes seem to switch with each other, as well as the biome particles.
