Thank you for this thread. I recently had to replace my Maitreya body (re-delivered) due a glitch from a fantasy skin that I couldn't resolve, and suddenly I had a neck seam that I had not had before with my Leleutka head. The ItGirls skin was the same shade for both head and body. The fix was to make sure that materials were enabled to the same degree on both, which I hadn't thought to check until reading this!
