Goofball trait
Do goofballs use only michief interactions in your game? Mine do all the time since latest patch. They don't use any other interaction, not even funny ones.

I do feel like they took a step in the right direction of making Sims feel more distinguishable and less samey when you play them, although a lot of work still remains to be done. These changes will take a while getting used to, obviously, but I thought it was kind of funny when my Goofball Sim pranked a toilet on his own. He also went off to flirt with his husband after, so mischief was definitely not the only thing on his mind. :)
