Were you able to get a crash id?
Sorry, it doesn't crash the game, just the editor stops showing changes.
And if you exit the character edit screen (V) and go back in, the character panel is blank - even after a restart, even after verifying files.
I can replicate it by creating a new character - whenever I go to the beard or face paint/scar screens it occurs.
Here clicking on a scar - which doesn't show up on the character, after this no further changes show up:
Before this, I can make changes to height, weight, face, nose, jaw etc. Only once I go to the decoration screen does it stop responding.
And here after exiting the screen, and when I return to the menu in game:
Edit: on further investigation, if I hit the randomise button a few times I get a new character appear... but that freezes again once I edit the facial decoration.
