We're going to bake the fix now and also subtract the mouth open morph.

Make sure that only these morphs are set as follows

Lipfix that you created with the morph brush should be set at 1

MouthOpenMorph that you created should be set at -1

File: Export: Wavefront Object. Alyson's head. All boxes unchecked as before. Call this morph MyMorphFixed. Export.

Zero Alyson. In head properties load morph target MyMorphFixed and dial to 1.

There's your original morph with the errant vertice fixed...
