Well, daggers were originally made stackable because people would make 10,000 daggers overnight and just let them fall. We put in some decay stuff to make them not stack above X amount in a single spot, but then people started using organizer agents, so you'd have bags of 255 bags of 255 daggers each sitting around. That by itself is 65K items that the shard would have to save. Making them stackable takes 60K daggers down to 1 item.

Since then though, there have been lots of problems with daggers stacking and causing problems, losing their exceptional mark, etc. I like my idea I mentioned above where we change the main craftable item to something unused that stacks normally.
