Ryanair & A Possible Double Booking #wtf

As regular Ryanair-customer, you get used to the way the low-cost carrier is treating its customers. Will not complain about that, what you pay is what you get and they always bring me from point A to point B, which is exactly what I expect from them. Until I double booked a flight.

Background, in my enthusiasm I booked one flight to Krakow twice. Stupid, I know, but ok, it happened. Will not nag about the fact that cancelling is  impossible , nor that changing the dates of the duplicate showed more expensive than booking a new one. So basically I took my loss and accepted that one of the two bookings was a waste of money.
But sending me a notification that I possibly booked twice for the same flight exactly three (3) minutes after that flight took off?
Really Ryanair, WTF?
