My people seemed unwilling or incapable of growing crops on the farm or the mushroom farm.
The mushroom farm appeared to be waiting for an injection of spores but I was unable to locate a source or how to do that. I built shock tanks and logs but they never grew anything edible.
The standard farm I'm guessing I didn't match the seeds they were carrying to the selection on the farm but it would be nice if the drop down grayed out or otherwise said hey, you can't actually grow that crop instead of letting you create a farm that would be ignored.
A hungry status or warning would be nice. My people just started falling over dead while I puzzled things out.
Fishing - Would be nice to assign someone to fishing for food. Maybe build a dock if you need it anchored to a zone. If its possible to fish off a bridge I don't know, I didn't try it but you should be able to.
