I think I know what you mean. I have the same problem. You made the item correctly, but the customer wont pick it up. Or you didn't make it correctly and the item doesn't tell you that.
If that it correct. When I know I made the item correctly, I just leave it by the front desk and a customer will automatically pick it up. If they don't, I know the order or customer is glitched.
If not correct, I am sure someone else will come around and see your post, or ask again on separate post. Good luck!
