Undefined Array Key Warning Editing Product Subject to Quantity Discount

[daphilli224]

PHP Warning: Undefined array key "category" in includes/modules/order_total/ot_quantity_discount.php on line 224 received when editing an order containing a product subject to a quantity discount. It appears that edit orders does not provide the product's category in the $products array that the order_total quantity discount module uses. In the order edited, although the product was eligible for a quantity discount, the quantity purchased was insufficient for a discount.
