I have both his plugins for Cinema - cr2loader and the morph tag loader. In Cinema, a dialogue comes up when you open the cr2 or pz3 and you have the option of what you want to load - you can choose to skip bones, skip morphs, props, materials, etc. No knowing if it's the same in Lightwave, the only thing I can think of is you might accidently have "skip bones" checked and saved as your preference.
