We figured out that we have had an issue the last few weeks where products are being ordered beyond the qty available. I was able to replicate how it was done and want to know if there is a fix.
We have our product that has 2 available total. The product has a single SKU product modifier of size. People have the ability of over ordering the product if they add different sizes to their cart. For instance if their is 2 packages left and they add 2 smalls, they can go back and then add 2 more mediums to their cart and checkout. When looking at the backend the qty is now -2 on our end. How can we get this fixed, so far it's been on products that aren't a big deal but we do have some coming up where it would certainly would be a major issue.
