Ideas
Just downloaded the fairies pack today and omg literally got attacked by gnomes. Just spawned in the apartment and there’s like 30 trash piles everywhere and every appliance and plumbing object broken. I found it hilarious until it happened AGAIN soon after I managed to clean up the mess! Like an sim hour later. Also why are the gnomes alive? From my understanding they only come alive if you have fairy dust to bring them to life. Also my sim is not a fairy and lives in san myshuno and has nothing to do with fairies so I was so shocked.
One of the ailments, gnome lure, can cause a sim to be followed by gnomes. Sometimes they are helpful gnomes; other times they are cretins. The biggest issue (which is likely worse in San Myshuno) is that they can also spawn when a passerby has the ailment, not the currently played character.
