I have no mods installed and have no edited any files. I made a rather simple landing parachute crane for a Duna rover. No thrusters or anything. Just some 'chutes and trusses. Anyways, it keeps randomly jumping like this then it will suddenly try to change direction completely randomly. It ruined my Duna Rover launch completely. I even rebuilt the rover and crane to no avail. Also, at one point, a random truss piece flew off, and when I inspected closer, I didnt see any missing truss pieces? Very strange. I attached a video of the anomaly.:
