@archaicvampire and @tarasirtis I've had this happen occasionally with new houses I build, usually after I move sims to the lot. The first indication is always that I hang an object on the wall, for example a certificate for reaching level ten in a skill, and it disappears. The issue doesn't seem tied to the lot itself, or the world: if I quit without saving and try again, the walls work fine.
So I don't think it's necessary to start a new save or anything that drastic. At worst, you could save the lot to your in-game library, evict your sims, bulldoze the lot, replace it with its library copy, and move the sims back in. If you did this in one Edit Town session, without saving your sims to the bin and replacing them with their library copy, they'd keep their jobs and relationships, although they would lose their promised wishes and opportunities.
