I stumble upon an issue tonight when trying to package Isabella : there was a reference to a morph inside your package. To be exact "Breath1.vmi", I don't know why, but I'm pretty sure that a content like that should not preload morphs (the checkbox saying "this package contains morphs" (or something like that).
The sad thing is, I'm gonna delete the package because it don't want this kind of things to happen :/
