I'm using Magento 1.9.24 and I have a tricky issue . When a file is attached to the order (I set the product with a custom option where the input type is "file") and the administrator wants to edit the order (selecting an order and clicking on the Edit button from the admin panel) the file is lost! Magento creates a new order with all the options chosen by the customer except for the file. Is it a bug? How can I fix it and let's the edited order contains all the custom option, included the file?
