This is happening to me. I'm in a Multiplayer server, and the camera shakes uncontrollably and the UAV keeps rotating in random directions.

This happens regardless of any waypoints

The last time, I was aiming at the top of a tank, at the turret, and it went over.

I'm also not sure about the distance, either.

I had a similar problem. I used all my artillery and UAV strikes on the armor, and everything missed, so I stole some launchers and charges, and hopped in some allied armor and blew the tanks up myself.
