Some Werewolf Body Scars causing weird lines on faces.

I was trying to make a spellcaster in CAS when I discovered that they have a very irritating line running across their forehead.
I removed my complete mod folder to eliminate potential mod problems, but it is still there.

It seems to be a problem with all Sims when they have certain body scars enabled.

See the image below:

As you can see their is a very feint line running across their forehead.
Has this been a known issue for some time already, or is this something new?

And any idea what to do about it?

Thanks!
