You can put infinites things in a shelve in Pz but that isnt realistic can you put 700 items in a shelve ? in real life you cant. I say that they can put a limit in all storage like boxes only 10 items shelves 20 , refrigerator 30 something like that to make the game more realistic and start to make a basement of boxes in your base ( what i said we cant make basements ). Ok that is all
