Nipple-distorted weirdness after converting a character from Genesis 1 to G3M

Okay, some weeks back, I converted a character of mine from Genesis 1 over to Genesis 3, using this tutorial over here, and after some false starts and after going through some hoops, I got a pretty good result, The one on the right is the original Genesis 1 version, the one of the left is the G3M version.  (I've used a completely different, G3M skin on the new version, with some stuff tweeked. Ignore the hair, it's the SAME hair, but for some reason it doesn't quite want to contour right onto a G3M head even though the HEAD shape is identical G1 to G3M.)

I'm mostly satisfied with the results... but there IS this one anomoly....  The nipples on the G3M version came out a mite... out of kilter.  It's like the outtermost edges of the nipple-area are twisted downward a bit, and the nipples are maybe stretched outward towards the sides slightly, though mainly I'm focusing on fixing the twist.  I'm hoping there's a simple way to tweek this back up into level again with some other, existing morph or something.  Any advice?
