Nifly doesn't read NIFs with skinned meshes without Vertex Weights in NiSkinData properly

[ja231c]

It works in Skyrim SE, it probably works in other games that use a NiSkinPartition too, it works in NifSkope, it works in the NifTools Blender NIF Plugin.

But it doesn't work properly in any program based on Nifly.

@ja231c nifly does load and save NiSkinData blocks with "Has Vertex Weights = false". There was a small bug when the vertex count in the NiSkinData was > 0 even though weights were off: d76bcf0

What functionality are you referring to that isn't working in for example Outfit Studio with NIFs that have Has Vertex Weights = false? Do you have an example NIF for me to test? How do the bugs make themselves visible?
