Bebop Flyaway

My Bebop did a flyaway, after almost 280 flights and over 20 hours of trouble free flight time. I'd had a couple of flights just prior to this with no issue but before that my Free Flight Pro app had done an update, possibly this could have been the cause, maybe wind or my 2500 battery pack? This shows why I never fly over houses, roads or people, fly safe! Let me know your thoughts below.
