Oh maybe it did then. It left the mechanism used which confused me.
Word to the wise if you're trying to irrigate this way - dropping ice from above onto ice floor nets you nothing, it won't melt. I remember reading something like this (build a Floor before doing it). Dropping a large hunk of ice into a cistern and then building your farm below that for gravity flow/floodgates is probably the simplest way to get this done. Since my first try at the farm is a failure the caravan had a meager 3 barrels of booze, and two waves of migrants rolled in like locusts, that fort is now toast Anyway that was a great idea, I'll definitely give that more time later on
