i have a sim in my legacy family with the good trait that i also marked as hating mischief as soon as i got the notification she gained the mischief skill as a child and she maxed out her mischief skill from autonomously trolling (and then pranking her siblings bc trolling gave her a high mischief skill). this was on a microhome lot and she has the scouting aptitude trait, so her skill gain was extra boosted, but she a good sims that hates mischief
(i have seasons, parenthood, tiny living, and the free holiday pack. i have lots of build/buy and cas cc but no script mods)
