Some day long time ago some one changed storages that they not deal death damage when you ctrl+k them (and they not do it)
(probably to counter SCUs that teleport in and build and selfditruct storages in times when storage were giving 2500 damage)
However when you use instant selfdistruct they deal damage, and now i am not even sure if it is a bug or feature cause i remember myself useing storages as sort of mines
discuss?
