I've got two things that don't work in the game. First is the inventor gnome, I was so happy when the Sim made an inventor gnome hoping that it will help finish some of the inventions, but it never has done that! Even if I let it sit overnight on the invention table. The next object that doesn't work is the mood enhancing potion, the Sims in the house sometimes have low energy and other low moods, when I let him/her drink the potion, I checked the moods, nothing has changed. Is it really like this? Thanks!
