Have airships with extended pistons. Everything works fine until the ship is disassembled. At that point, all the front part (the part that extends) of the pistons to the left of the helm disappear when the ship is stopped. Turning the power to the piston off and on fixes it.

Picture taken across centerline of ship, so you can see both affected and unaffected pistons: http://harmonyware.com/pictures/2020-09-05_08.53.08.png
