Same thing happened to me... I purposely did not tap my box until last evening so that the twelve hours timer could work over night and I would have more time during the day to fill the orders...
So when I opened the box this morning I had a 17+ hours timer and was pleasantly surprised that the recipes I had cooked last night (after starting the box with its 12 hours timer) seem to have counted... Then when I returned I few minutes later to check what else I had to bake the order had expired!!! And I now have a waiting period of several hours before I even get the new order
