Ovens disappeared

[zudi]

I was under "design mode" moving my ovens back to storage in order to put my stoves in and suddenly a messages appeared and said my restaurant was out of sync. When I reconnected, my ovens were no longer in my restaurant nor my storage. I used to have 6 basic ovens and now I only have 1. How can I get my ovens back?

There isn't any way of them returning, but I have had the same thing happen to me
