So I whilst trying to convince my colonists to build a water source, 12 of the died from starvation because they're too stupid to do as they're told. One of them died on a ladder and fell to the bottom of the prospective water source for purification, and subsequently drained it all. I've attached an image that shows the water flowing directly into his corpse.
Something that I've noticed is that duplicants will constantly fill up the microbe musher, even past the minimum needed to make food and keep filling the microbe musher until they all starve. They will also put menial tasks like botany and resource collecting about eating despite the microbe musher being set to priority 9 and everything else being priority 1. Has anyone else had this issue with colonies?
