Reposting from the PC thread:
Unfortunately, the same thing has happened to me. My female agent's face got changed to the Female Default 0 one after visiting the barbershop. Also, I've noticed that the enemy NPC now refer to my agent as a "he" too.
It seems that this bug is tied to the barbershop. People have reported on Reddit that their character's race/gender/face got changed after paying a visit to it.
My character's face was also changed to female default 1. At a glance, it looks like everything not associated with the facial preset and customizing is intact. Hairstyle + color, Tattoo, facepaint and the like.
The change occurred after today's maintenance, but based on what others are saying, it may have just been the signing off because of maintenance that triggered it.
Don't want to reroll, but I'd rather do that than keep the face I didn't make.
