There is simply and logical change.
Storage store mass, when someone lose storage should lose also mass that is stored inside (that is logical) not only max amount of mass but also that % portion that was stored in that concrete storage.
When mass storages is destroyed realse wreck with mass. And this mass should contain also portion of mass that was stored inside (that is also logical).
Taking this storages can be a tasty treasure when destroying storages, so mass will be less abstract magnitude but something that is more real and ready for reclaim.
half of this is in some mod that I will not name here.
