"Well, I loaded it up in P5 and as expected the morphs were not present and the dials didn't work" Sounds like you didn't turn off the "Use external binary morph targets" option in the preferences before saving the .pz3. That's why the dials for the morphs don't work. If you have the option enabled, then it saves the morphs to an external file. Disable it, and all the morph data gets stored normally the next time you save a scene.
