Faced a very erratic crash with my drone. After completing a mission when the drone was RTLd, came back to home position and came down very fast. At much higher speed than the set 1.5m/s. Crashed onto the ground breaking all my landing gears but to my surprise it started climbing again. Climbed to a height of 95m before coming back down again, and crashed and disarmed. Kindly help me understand the issue here. Attaching the telemetry log for the flight.
