Zero subtotal leaves the status in pending

Seem to be having a small issue with people ordering free blueprints from WoodMarvels.com, the blueprint link is shown but is always pending without any way for me to process or change the order in my e-com program.

The only fix I am aware of is adding a price so I have had to change the pricing for the Zulu Main Battle Tank and Medieval Castle Walls B from free to 1$ as now, I have to deal with Paypal charges as well. Hopefully the next update fixes this issue so I can make them free once again.

Update: This is a bug with Magento, as a result, I will be performing an update and returning everything to free.
