After I expanded my restaurant and bought a commercial oven, my restaurant doesn?t earn money anymore when I?m not in game. All the dishes are piled up on the counters. I can?t make new dishes because no customers spend money in my restaurant. The ?how much money I have earned? sign doesn?t pop up anymore whenever I play the game. How can I solve this problem? I tried to delete and re-download the game, and it?s still not working.
