Locked Piston can extend on loading scene.
1. Load "Lock Piston Bug.sfs"
2. Hold down 'H' (translation Forward) for a few seconds which the pistons are bound to in the action menus
Can do it via Space Center or tracking station as well.
Note: Doesnt happen on retracting.
Not sure if the pistons target extension should be moving when its locked and hidden from the player.
Should at least be an option to have it not change its value maybe when its locked.
