This has been fixed (again) in Patch 1.19.31
Existing clowns will not be deleted.
Check on their names and delete them through your household manager.
He's basically a regular townie. He should only show up when summoned or on retail/restaurant lots.
So try summing him through the painting to see if it's the same one.
I don't know if this is related, but my John Burb, who was supposed to be a genetic mix between Brad and Tiffany, came out with blue eyebrows. I had to readjust them in CAS before I started playing the family.
Why do you think it's related to the clown hair ? Sounds odd.
Are you using any cc ?
Not sure if this is still open but when I got City Living and started a new game with no mods/CC - at least 4 Sims with the clown hair spawned in San Myshuno. I got rid of them by finding out their last name and deleting them in manage worlds.
Should be fixed and I haven't seen any in my game.
Were they re-generated or was it a one time thing ?
