Paypal express checkout issue...

Not trying to hijack this thread, but I have been using 1.3.9h and paypal express.

After 100 orders I have had my first "lost" order. I received payment notification but no order is present for the customer in our zen-cart.

Everything has worked beautifully so far, I even believe the customer used the same address for shipping as their bill address and it's confirmed. I just wish there was a way to track why this happened or at least make up a mock order for them so it's listed in their account.
