No Ground Textures with Sky on Simple/Complex?

[Qaldar]

If I turn the sky on simple or complex, the ground texture is completely gone as if my character is running through air. The walls and sky are all still fine.

If I turn the sky off, the ground shows back up and I can see it all the way to clipping plane edge perfectly lit even if it’s night as a human with no vision.

Please help me get my ground textures back with sky on!
