[RWK] Sims always thinking appliances are dirty

I bought the Restoration Workshop kit and placed the new appliances in my sims house to work on them, immediately afterwards all my sims and NPC sims thought my all of appliances (toilets, showers, sinks, fridges, ovens, coffee machines, etc.) were dirty, even if there was nothing visibly wrong with them, and the only way to fix it was to delete and re-buy all my appliances.
