if you have to many items, and your stockpiles get to big.
I have a fix for you!
I looked through the forum and coulnd find anyone with this Idea.

Looks like a normal building
How to create your own:
- use slabs to build higher,
- have 3 blocks of air between them (3 works, havent tested with fewer than 3)
- place the stockpiles
