{SOLVED} Issues with split edges on the hairline of a mesh

Hey, I'm having issues with a seam being caused along the hairline of a mesh. When I am importing the .blend into S4S there are no split edges so this point should not be able to morph separately and show a seam. No matter how many times I remove doubles and even import a new base game mesh and fit it into this area it shows this way in game. I also notice, if I export the mesh from S4S, there is a seam here that I have not put there. Worth noting, it only shows on certain sims such as the last male face template.

 


I can't seem to figure this out. If anyone knows anything I'd love to hear it, thanks for your time. Here's a download for the .package and .blend files
