Jon Snow's hair sometimes disappears at Craster's Keep quest triggered

[tos1]

I tried from a few saved data one or two in-game days before the Craster's Keep quest is triggered, and his hair unstably disappeared 4-5 times out of 10. In case I saved the game just before (about 0.5 days?) or after the quest accepted, the state seems to be kept. I don't know the issue has existed since v9.3 or earlier, but I've never seen his hair look like that before.

- How to reproduce it/when/why it happens:
(Unstable)
Complete all North quests up to the point where you encounter WW and talk to Jior. Save the game frequently. Select "Sure, let's go.".

You need to have about 2 or 2.5 in-game days after the last save before the next trigger where you receive the message above. If you used save data just before the trigger (about 1 day), it seems to cause a fixed action, i.e. the issue always happens or does not happen.

The correct face code is not assigned for some reason here. I use the native api call to do this, but it seems it does not always work. Potentially a bug in native code.
