Having the catagory of items grouped together under Weapons, Resources & so forth is stupid. For example, Ammo. I set 128 as max stack size for ammo. But it also allows people to stack 128 of rockets, which is not what I wanted. The old layout of individual stack sizes for items was better. This way, it allows me to specifically balance the server by item, not by catagory. 

But of course, If you like having players running around raiding people in 1 go because they've stacked a load of explosives & still have room for loot. You've hit the nail on the head!
