My resturant is not functioning because guests dont stay seated. Most of them leave the restaurant after being seated.

Please, The Sims team, I kindly ask you to fix the Dine Out Game Pack by making Sims stop moving around in the restaurant and allowing them to remain seated at their tables while waiting for their orders.

Edit By Crinrict: Adjusted Title fit bug report at AHQ

when I have my sims go to a restaurant, they stand immediately after they start to eat their order, and refuse to sit down while eating it. the action queues but is not fulfilled until after they finish eating and put their plate on someone else's table.
