Problems with render Tweet

[GalacticGhost]

So in the image below I have noticed that there is a region that is not rendering correctly, as you can see her left eye isndiscolored compared to the rest of her. At first I thought it was the scope somehow, but hiding the rifle and scope does not remove the issue so this means shader issue, I am guessing. Other than just doing post-work, is there a way to fix this or is this a bug?

Invisible geometry in the hair prop may be causing this. Try reducing the Kernel->Ray Epsilon.
