mmm the crate is broken. it make it so you can get unlimited items.... every 10 crates make it that you can store 100 more items even for crates. It's a positive feedback loop! you will never run out of storage if you keep making crates!
I do like the new tool crafting mechanic where your dwarfs must make items to get better expeditions. this make it more like a recourse management game then an incremental game.
