Neck Seam Caused By Texture Mismatch

[xXeeeeXx]

I reinstalled Skyrim to give BHUNP a try and got a neck seam. The only skin textures I'm using are from the "Fair Skin Complexion" textures packaged with BHUNP . The attached screenshot is my modlist. I've tried reinstalling the game and trying other textures to try to fix this problem. Any help would be appreciated, thanks.

open racemenu

scale body to weight 100 (gap should be gone now)

export the head in the sculpt tab

scale body back down to desired weight

go back to sculpt and import the head exported in (3)

exit racemenu
