Error on Optimize SkinnedMesh with Unity Plugins. Unity version 2021.3.12f1

When I tried to use instaLOD to optimize some skinned meshes, I receive some error message about their bone weights like below:

WARNING: GenerateRemapBufferForPositions: not remapping vertex 752 to 756 due to bone weight mismatch.

And the optimized meshes were deformed with or without animation.

I've already tried some different settings like making SkinningImportance highest, while other lowest. The amount of points in warning changed, but not removed.

So what could I do to work around this? Does this related with blendshape or some other features?

Many thanks.

  Hello,

   

  I haven't seen a warning like this in Unity generated by an InstaLOD operation before. Does your mesh contain more than 4 weights per vertex?

   

  Thanks,

  Yes, currently most of the vertex has 4 weights. I haven't check those meshes yet, but the project has limited this to 4 and the conversion was used Unity meshes.

  I think it's not related with the meshes themselves, as when I tried to reduce to 40%, there were much more error than to 80%. I could provide one fbx with most serious problem.
