Unsightly seam in male Hawke's chin

It's difficult to judge without screenshots, but is it possible his teeth are clipping through his chin? Is this with any custom Hawke, or did you only encounter this on one specific model?

I took a tiny video and made a gif to show the problem, as a screenshot might... overstate how drastic it is. This isn't the worst it gets, but it's an easily available and repeatable conversation. I've tested it with an unchanged preset, with and without a beard, and so far the only case I've seen where it hasn't done this is with the original default Hawke pre-set; my guess is that it uses an entirely different model or otherwise the beard simply covers the seam better. As you can see, it's not teeth clipping through, it's like one or two vertices in his chin just don't get the memo from the lip files when he speaks.

Turns out the HQ doesn't want me uploading it, so here it is on imgur: http://imgur.com/Q9UtIVK

After a little bit more poking around I found another oddity: A saved game that I made about a year ago (using roughly the same face) doesn't seem to have this problem. I'm wondering now if somehow the game is assigning the female Hawke's lip files to the male one. Though I have no idea how that would be happening even without mods installed.

Edit: I've been working on this a few more hours. I can copy an appearance over in a save editor from a save made sufficiently long ago and import the MORPH file directly. Assuming the character was made before whatever is causing this bug (I'm guessing .NET shenanigans) the face imports more or less gracefully. It's not a solution, but it's sort of a patch.
