I can't kill my companions after I recruit them.

[MurderinHenry]

They literally become immortal and immune to my bullets. Why? After I dismiss them from the ship, they literally disappear into the void as well, nowhere to be found. Please fix this, give an option to turn on friendly fire and have they just walk away after they leave the party. 

[Ommamar]

I have had them take damage from my weapons so not sure what you are talking about, I don't play on super nova so at the most they would just be disabled.  Why don't you just not use them instead of dismissing them?
