Issue description
Although the recipes say that concrete mixers produce 12 concrete slabs, watching the items come out on the conveyor, and how many are added to storage, it's clearly 8. Screenshot attached.
Clearly a minor thing, but reporting it once I noticed. Great game! Keep up the great work!
Reproduction steps
Should be pretty clear from the screenshot below -- 8 slabs coming out of the mixer only.
