Mouth won't open because of hair?

[Riot445]

I have YPS installed, my game v is 1.6.1170, and when any scene involves oral while I have a hair from Dint999's "HairPack02 HDT" equipped my character doesn't emote at all.  Outside of a SL animation they regularly change facial expressions, just while in an oral scene they remain stone-faced.

type showracemenu once, u don't need to make any changes, confirm and bug should go away.

Update your Dint's hairpack. Some of his hairs had a bug which stopped facial animations.
