So during the companion guild quest, when the werewolf transformation was over, I noticed that the haircut of my character wasn't the same...
My character is a nord, and it seems to reset to the default redguard face and haircut whenever he transorfms back to human form.
Does anyone has the same issue or knows how to fix it ? thank you and sorry for my english

Please I can't be the only one with that bug

I can tell now that this issue occurs because I used the command "showracemenu" and changed the race of my character during the game. And after the transformation I can use the command "setplayerrace 13746" to recover my normal face, but it obviously mess with my perks and my skills.
So I wonder now why the game still consider my character as a redguard when he's transforming back to human form, even if I changed it to a nord before that ?
Any idea ?

Btw please forgive my english, this is not my native language but I think its still understundable.

I've found something that seems to work well, so i'm posting it here and maybe it will be usefull for someone else

After being transformed back to humain form, use "player.setrace argonian" and THEN type "player.setrace whateverraceyouwant", your face should be returned to normal and your stats should be unchanged ! Worked for me at least.

The problem in script
"PlayerWerewolfChangeScript"
Game.GetPlayer().SetRace((CompanionsTrackingQuest as CompanionsHousekeepingScript).PlayerOriginalRace)
If you used the command "showracemenu", it becomes not a new race, and that which is specified in the parameter "PlayerOriginalRace" quest "CompanionsTrackingQuest".
I added a solution:
