When placing product order with attributes. The store is checking stock by the Product and it's Attributes instead of just checking by Product.
I have an item "Custom 14 Karat Gold Namepins Round Wire" with a stock of 1 item, the item has 3 attributes fields "NAME", "CHAIN", "CHRYSTAL HEARTS". the Namepin is priced by character by the name field.

If you add more than 1 item to your cart with identical attributes an error "(Products marked with *** are out of stock)" will appear. if you change an attribute or the name on the namepin, the item gets added to the cart. The problem is I only have 1 product in stock.
