Took a look - holy cow! No wonder it said over discharge... It was drawing over 310 watts / 27 amps out of the battery - You can see in the graph on the bottom left that the motors were having to work a little harder to hover as the flight progressed but even running 4 motors flat out shouldn't draw that much power from the battery. I'm assuming you had some sort of short due to condensation of fog in the motors (didn't think this was possible because the windings should be shielded...) - may also be an internal short. My advice would be to (if it's flyable) wait for a nice day and have it hover ~3 feet from the ground; if it was the fog nothing will happen and you will be free to go, however, if it is an internal short and it has a similar issue you should contact dji immediately for an RMA ticket.
Hope this helps!
