Harmonia Backorder

I ordered a few things at the beginning of this month, and two of them were delivered on time - the one that wasn't was the Harmonia. It was in stock when I ordered, but when I checked later it was out of stock and the item was labeled 'backorder'. Now it just came back into stock, though, and I'm wondering if they will just ship it like normal, or do I have to file a support ticket or something?
