Chef Stoves Restaurant City Glitch?

Restaurant City glitch? - chef stoves

In the restaurant of the city, my boys and cleaning products are added in front of the restaurant, near where the market is. When I look at these people, "head" back on the outside, but people will not just be there. Only the cooks were standing in their kitchens. Nothing works.
I update the site, fed all the workers tried another browser (Internet Explorer), then restart the computer, asked a friend to my account on your computer and check contact if it is good, and was even asked Playfish while, but so have received no response.
Can someone help me ....
