[Bug]: Alex's Caves biome_sky_fog_overrides causes visual issue with tar from Unusual Prehistory 2

[ecoterrorist]

What had happened?

With Alex's Caves and Unusual Prehistory 2 installed with default configuration, swimming/sinking below the surface of a tar pit from the Unusual Prehistory 2 mod causes a visual effect akin to night vision or high gamma. What should be complete darkness under the tar is pure light and 100% visibility.

Toggling the biome_sky_fog_overrides parameter in alexscaves-client.toml to false resolves the issue, but having to disable a feature is not ideal, and cheapens the Abyssal Chasm immersion significantly in this case.

Here is a screenshot of the issue. In the screenshot, I am fully submerged in the tar pit, and should be able to see nothing at all.
