So I have a figure built on the David base, but when I go to save it in the Library, the teeth go all monstrosity, and it looses all the full body changes I made.

The images show what happens to the teeth. And I don't just mean it saves to the library like that, I mean, it actually changes the model in the open file I'm saving from.

This one is driving me insane, because I've already rebuilt the character three times.
