Data overrides fixes
assets-meshes/mesh-fix
referenced the non-existent category assets/mesh-improvements
, reflecting the fact that it's one of the oldest packages on here.
assets-misc/morrowind-optimization-patch
had a couple of TODO overrides, for packages which at the time weren't in the repository, but now are. I've added the one for correct-uv-rocks, while project-atlas already overrides it, so the underride isn't needed.
