A LOD model with a path that does not match from meshes\lod\* or meshes\[new world|mod name]\lod\* was found.
Mods should be following standard file and paths naming conventions established by Bethesda for better usability and compatibility, especially when being part of the cathedral modding concept.
LOD models that do not follow standard file and paths naming conventions established by Bethesda may not be automatically detected or matched to full models or cause things to not work correctly that depend on pattern matching for example.
If a mod depends on DynDOLOD to generate LOD for it, then it needs to follow the conventions established by Bethesda and as expected by the tools to avoid issues. This is the same principle as using the correct terms and values for INI settings for them to work as expected.
In case there are any issues with the LOD model, including its LOD missing entirely or it having wrong textures, move the LOD model file to an appropriately named path as explained in How to add your own object LOD models and generate LOD again from scratch.
