I have zero idea what is going on here. This glitch does not show up in the preview window, only in the final render. Any ideas on what could be going on? I removed all expressions from the face, tried it with a different character and tried it in a different scene. Same result.

Oddly enough, it does not happen on the kids with their CC2 bodies, only the adjusted CC3 kids. Is there anything I can do outside of returning to the CC2 bodies? As the bent elbows on CC2 looks pretty ghastly too. I will try to take mesh smoothing off the CC3 kids and update with those results. As I am hoping it is simply a glitch in the Mesh smoothing process and not a glitch with CC3 and the child morphs.
