Well, I followed their directions, and I'm patched and my (challenge) game is running fine. I just added back my CC stuff. I can't tell from the names what they are, sadly. My crazy Sally likes to wear this shirt that I just loathe, usually just with panties or a bikini bottom. The shirt's got to be CC, but it's the first time I've seen it, so I guess I could be wrong. Maybe they have hidden wardrobe items only Sims with particular traits can wear, because she was still wearing it (not to mention showering in it) when I had all the CC removed. Oh well.
I'm thinking that I should load up the game I was playing right before I started the Challenge so I can see if they fixed being able to put your design sketches in your portfolio as a Stylist. I've reached the top of the career in that game, but my portfolio is only 52% full. Okay, this is almost certainly off-topic. If I post on it again I'll put it where I should. Under Ambitions, I think?
P.S. What the Mysterious Gnome is a "laundry bear"? Better not be that saccharine bit of fluff that sells fabric softener.
