What a clever idea, ClayMask! I suspected it would be something along the lines of a repeating wish. I did something similar, though with less commitment and therefore far less dramatic results. My Sims would roll regular wishes for pillow fights, as all Sims do, but then they would roll it again as soon as it was satisfied. It meant stopping them and asking them to start again, but I took advantage of that when it happened. I also bought certain items they wanted, then deleted them so they could roll the wish again. I can't tell you how many kid ovens I bought. I wish I'd thought of that sooner; it would have been quite easy to have a minimally furnished house and buy objects as they were desired and delete them to purchase them again the next time.
