Do you have "Use External Binary Morph Targets" enabled by chance?  These do not work with V4.1 very well at all.  If you open the PZ3 or saved CR2 in a text editor, you will probably find your morph deltas with an amazing array of crap instead of real morphs.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
