An odd error occurred overnight where an error in OPC caused duplicate orders 22 seconds apart for the same customer and same items, but did not send out any order conformation emails. Only one of the orders was charged out (PayPal) with no payment confirmation visible in admin, but shows in PayPal.

Same error posted to the log for both orders.
