Problem: When the root part is NOT on the rover it will hover in place when decoupled unable to move. While I do have mods installed there are no modded parts on the rover. When checking the ingame console I saw that the following was being repeated indefinitely until I reverted flight or quit the game.

I have never had this problem with a craft before. I am using a hinge from one of the dlcs as the main body of my rover. Any help appreciated. All mods up to date.

After deleting all mods and doing a full stock reinstall of the game I have determined that the bug is from the actual games(most likely a robotics part) NOT from mods. I will move my issue to the appropriate thread.
