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.
Now that I have dine out, I'm seeing the clown hair everywhere. When I go to edit the sim, it isn't in CAS. My restaurant has had up to 8 people with clown hair – they always outnumber the ones without.
I'm having a problem too. If I go to edit the sims with the clown hair, their 'normal' hair is in CAS. Even if I save the changes and exit, they still have the stupid clown hair. Looking at the list of sims to add to a club there are two in actual clown makeup on the list and at least two with just the hair attached to them. Not sure what's going on but the hair shouldn't be attached to these sims, especially sims I've edited personally and KNOW what hair they had on them (and, again, the proper hair shows in CAS but won't 'stick' on saving and exiting CAS, they will still have the clown hair).
This is a new save since installing Dine Out. I didn't play with the previous patch where the tragic clown was introduced.
