Issue #32392: Invalid texture path in waterkelptall01 mesh
The mesh located at meshes\landscape\grass\waterkelptall01.nif has a broken texture path, looking for a nonexistent folder called "NOR". I have no idea what this should be pointing to, if anything. Possibly "textures\effects\coastkelpgrass01_n.dds"? That's what is used for that property in other Kelp meshes.
See attached screenshot of the mesh loaded in nifskope.
