An update after a little more testing.

   Resaving the clothing does work, BUT only if you load it into a "clean" scene. If you have V4 in the scene, even if you delete her before you resave the clothing, it doesn't seem to work. At least, this is what I have found with the V4 MFD and the Selene dress.
