With respect to the method PhilC suggested, while improved due to the inclusion of the XROT adjustment I had omitted, I get the similar results.  Its not tilted, but a partial pose saved from the figur (memoriozed at Zero with the XROT adjustment and Z, Zero X with Y at DROP to ground hight), will cause same figure restored, to sink into ground to ZERO Y when the partial pose is loaded.  By partial pose, I am saving the pigs ears in teh back position, and adding to pose library with just head, and both ear (and ear hair) groupings as selected subset.  I woudlnt think a loading a partial pose affects body world translations.

Wondering as I write this... Could there be something in this CR2, like an errant morph channel that is causing this translation upon load?
