Something odd must have happened when I ordered my sim to prepare dinner. She didn't prepare it the first time, so I ordered her to again. As she and her family were eating, I noticed the first food tray on the floor. I tried picking it up in buy mode only to find the tray was "in use." I ran into this problem frequently in the Sims 2 and usually solved it by activating "moveobjects" and deleting the stuck object. However, Sims 3 will not allow me to delete the glitched food tray even with "moveobjects" and my sims can't clean up the tray themselves. Any suggestions?
