@ani_fl00 Maybe townies are sleeping when we don’t see them. 😴 There are people working nights, so maybe sims walking by your house are on their way to/ from work. 😊
The day/night update was a year ago and don’t know if it was considered to change logic that townies wouldn’t walk by during night. Players do need other sims to be around when doing for example quests & hobbies, so it’s good to have other sims to play air guitar with or talk about gnomes even in the middle of night. 👍
