If you embark on a site with Clay Loam, or I think any kind of Loam, you don't need to irrigate your underground farms. Just dig them into the Loam. (I just did this today. 
)
Whaa? I just failed then, since I irrigated loam into... muddy loam before trying farm.
Also, I accidentally ordered 30 brew drink commands, but forgot that each brew drink gave multiple "ales" and so now I have too much wine.
