The only time (besides masks, as was already mentioned) that I've seen something like this was when I had set aside a copy of Morrowind for testing my script work. I created a character with Better Heads enabled, used one of those heads for the character, and then removed the better heads mod. The result, upon reloading the save and clicking through all the errors, was that my character literally had no head.
I'm not sure if this could happen with NPCs too -- did you recently uninstall any headpacks?
