Flew my Mavic using Litchi after applying all the updates (DJI and Litchi) for about 90 mins today. Great fun without a care in the world until what I thought was a bird attacked the Mavic causing a sudden/short drop in altitude and loss of reception. Could not have been more than 20 seconds...a little freaked out I gained control and, as I was only 1,000 feet away, quickly landed and checked for signs of something to explain what happened. Nothing...not a scratch, feather...zip. About 20 mins later I'm hovering the Mavic 15 feet away from me and I watch the Mavic's gimble begin to freaks out ( moving up then down, left/right) and then the Mavic starts twitching turning right quickly then suddenly drops six inches downward to the ground...I wasn't touching the control sticks.I brought her down and switched back to the DJI app without further incidents. Has anyone experienced this since the updates? What could have caused the problem?
