"Morphing tool Create mode: Fixed a problem with morph mirroring when deltas along welded body part seams were not in sync."

OMG, if that's what I think it is, it sounds like they fixed the splitting on symmetry problem!
Big thumbs up to Steve, Teyon, SM, and whoever fixed it if that is the case :-)

I look forward to trying it but it proabably won't be until after Boxing Day now.
Thanks for posting, Hornet!
