I have built a webstore using 2.0.0.0, generally it is working great except one thing, could be a bug, could be me!
When I sell an item the stock level decreases as expected.
When I update the order to "shipped" the stock is then taken once again.
E.g. I have 10 widgets in stock.
Customer buys one widget - stock level now 9
I post widget and mark as shipped (with "notify to customer" ticked) and the stock level now becomes 8
This happens on every sale to all items and is ruining my store at the moment

Any ideas guys?
Thanks in advance
