[FIXED] [DO] NPC Sims Not Eating in Restaurant

I know no one asks for the save file, but for the sake of quicker fix. Here is the save files: https://drive.google.com/open?id=1gRrKHaWBrgEfHp2Q1HuBZmBYHlbuGBAd along with 3 videos to show various issues I encountered when opening the restaurant.

Restaurant bug 1 video

• 0:01 Waiter deliver foods to the table, she does the usual animation, but foods didn't show up on the table. I also didn't receive money.
• 0:06 Waiter deliver foods to the table, and the foods do show up on the table. But nobody sits down and eat it. At 3:03, Octavia Moon finished her foods and left the restaurant, the foods that delivered at 0:06 also suddenly disappear even no one eats it.

Restaurant bug 2 video

• 01:26 Food instantly finished after customers sit down. No drinking and eating animation.
• 04:41 Two customers do drink animation only but the foods also finished. This is kinda not realistic, there should be at least few eating animations. This one isn't a big deal, but I still hope it gets fixed.

Restaurant bug 3 video

• This entire video show Thorne Bailey family didn't eat the foods but finished their drinks. He and his son literally doing nothing, no talking at the table, no eating, literally nothing. While his wife signs an autograph to someone, then standing at the same place forever while she is supposed to be back to her chair. As you can see, no matter how long they are at the restaurant, the rating stuck.
• 2:10 Customer left without finishing her foods. She didn't even do the eating animation.
• 2:35 The guy that sits with the previous customer also didn't do eating animation, foods not finished too. This will probably make the game assume that table is empty now even if there are still unfinished foods because the customers have left the table, and if new customers appear, Host may seat the new customers there. Since the foods aren't finished, waiters won't clean it up. Making the new customers sit on that table with the previous customer's foods. For more details, look at reply #8 in this thread.
• 07:21 When I closed the restaurant, all unfinished food on the restaurant suddenly disappear like it's finished.

Hope the save file will help TS4 Team to find the solution quickly.
