Also probably not a bug. When Blucher sank at Dogger Bank the one gun she had in action as she heeled over was still being worked by some brave but foolhardy soul(s). Some crews were brave to the point of stupidity in extreme cases (e.g. Rurijk at Ulsan). Also there are a number of reports of ship sinkings in various wars of guns firing off as the ship rolled over, this is possibly the ammunition cooking off as fires in the hulk move into new areas as the stresses in the hull force pressure about in odd ways.
