Decided to do a quick mission after taking a small break. On landing I touched down and rolled a little ways when I suddenly got a warning for a hydraulics failure. I'm at a loss here as to what caused it or if it was just a bug? I attached the track, so hopefully someone can figure it out. I know I touched down a little hard, but I've done worse with no damage. Please watch track before commenting. No tail strikes or any that I could see that caused it. Hydraulics failure.trk
