"As before, Angelouscuitry, the scene that gave the trouble is now at:"  

Oh, yeah, woop.  Yep there are plenty of Figures; probably none with extensive morphs, but most likely with those that have unused morphs.  For future referrence SVDL has a pthon called RemoveMorphs.py  It will remove all of the morphs, of a figure, that are set to 0.  I managed to reduce my V3CharacterStusy.pz3, from 250MBs, to about 80 with it.

There is also more, if you interested in making themost of your new purchase, but we'd need a screenshot of all the Render Settings.
