I think there should be a way to rollback an action such as accidently shooting a missile at your own ship, or protection against such. reason i say so, is i made a little fighter ship, and thought i would shott the missiles into random space, they then made a bline for back of my larer ship, which ened up destroying the weapons core and salvage beam computer, so i have to replace the huge ass salvage cannnons, and i forgot to save a backup of my ship at all
