Yup it's happening to me too. Everyone, each and every single sim just stands around after entering a building, or a room, or before or after or while in the middle of completing a task and will take several seconds on in-game time to show me just how utterly and hopelessly BORED they are. Several times with the same sim, in the same room, in the same house I've seen snapping their head side to side with that dead-eyed bland expression and exaggerated sigh. It's so bad in fact the devs ruined the game so badly with this last bug that not even MCCC's disable emotional idles will fix it.
