Blender 2.79: Issue with Texture Painting The previous model I did had no issues with texture paint, it worked normally, but this time. . .not so much. I've looked through other solutions on here and various websites but I can't seem to fix it.

I've already:


Unwrapped and created an UV Map
Set up my nodes (crtl + T and Shift + crtl + click for textures) and
hooked up my UV map to the Image Texture node. Made sure everything
to the left of that node was set up appropriately. Followed a tutorial to 
make sure this was right
Made sure the texture in Tools tab in Texture Paint is off.
Checked slots tab and made sure everything was set up fine.


I can still paint directly on UV Map and when I try to fill the 3D model itself, nothing happens. The oddest thing that just cropped up is that when I paint the UV Map, the preview area becomes completely white. Never had that happen before.


Blender file here.

Any help would be greatly appreciated as I've been trying to fix this for the past day with no luck. I'm also working with the top half, the human half, only.
Found the problem area (due to some help on another forum), which was a slight overlook:
