It could have been a party, or just an invite from the phone. With the new zip I just invited the sim over by phone... to 'hangout'.
If you paint the mural on the wall, (lvl 10 painting) as an 'art style; stick figure', when the mural is clicked there is an option "sell for cost" but clicking it makes the sim just wander around the lot for a while before giving the shrug shoulders animation... going to try this one with a group of sims on the lot.
Tried again with invited sims over. Same thing, the sim just wanders around on the lot, before shrugging...
I've tried your save and all was fine for me. I did see the painting but I just removed it and after that I actually never had a NPC paint even tough I made it a club rule.
I'll tag this as Feedback for now to see if other users see similar behavior.
So far no one else seems to have chimed in.
Did you make a thread at the official forum as well ? There's usually more users posting.
