[1.4.3524] Vanilla, no DLC. Pawn with coloured hair no longer has coloured hair.

Loaded the game before the update and hair was pink, today after loading the game, pawn "Reindeer 60th prisoner" now has brown hair.
Tried restarting the game, putting on a hat and taking it off. No change.

Actually, a lot of hair has changed. "Clark" has a white beard that is now darker and many other colonists have had a shift in hair tone I can't quite put my finger on.
