Mesh "sticking" to vertices When I add a subsurf modifier the mesh "sticks" to some of my vertices as if there was a double or mean crease add to it, but I'm very confident there isnt either. This has been happening alot recently and is very annoying. If anyone has any ideas I would appreicate it. 
P.S-  sometimes deleting the vertices then recreating it fixes the problem and sometimes it doesn't either way it time consuming and not ideal
The normals were flipped the wrong way.
