It is possible to get stuck in a piston that is part of the power relay crushers in the Subpower Core room in the Voth Fortress Ship. If you have the Invincible trait active and are caught between the pistons when they come together, your ship will not blow up, but you can get stuck in the bounding/collision area around one of the pistons and cannot get out, even as the pistons move up and down. You can fly around that single piston, but not out of it.
I tried the /stuck command a few times but while it seemed to move my ship slightly, it did not move it out of the piston. Eventually I was able to shoot a decoy subpower core, and when my ship blew up it respawned clear of the obstruction.
