No not just that. when I used 999999999 force separators on a battle cruiser, the ship literally was torn to pieces. Here is what i believe happened: the projectile glitched and instead of going away from the ship that fired it, went towards it and phased through several fuel tanks, then the collision damage caught up with the projectile and tore the ship apart. Ill see if I can replicate what happened, as I still have the cruiser as a saved BP.
