Not sure this is a bug or not. When you move items from storage (silo/house/shop storage) to your inventory/disk/pet and you attempt to move more then those can hold, what they can hold gets moved.

From vault if you try to move more then inventory/disk/pet can hold and none of what your moving is already there nothing gets moved, you have to split off a smaller number that can be held and then move.

If this isn't a bug, could we get it changed so vault items act same as items in silos/houses/shop storage when attempting to move more then can hold?
