Table order disappeared while Change Table

Dear friends

Yesterday I had a strange bug, one order with 5 drinks disappeared while using the “change table” function. I tried the repeat this bug, but I could not replicate that error.

Anyone of you have an idea or similar experiences?

BTW: I use 1 PC Wind 7 (Server), 3 mobile PAD Acer (Waiter) and 1 Asus Tablet (Cashier), all connected via wifi
