So I was about 40 days into a gravship crew playthrough, and I had just landed on this beautiful peninsula with archean trees and silver galore. But as one of my colonists go out to mine something on a little rocky islet just slightly off the coast of the peninsula, I get a message in the bottom right I've never seen in my roughly 200 hours of Rimworld: "Colonist Drowning 0,7 hours left". And despite me sending my nearest colonist up to rescue the drownee (I should've in retrospect made them take off their gravsuit lol) the drownee died long before they could've been rescued.

In the moment I was just dumbfounded. How could this even happen? My most likely theory is just that they collapsed from exhaustion in a very unlucky spot, but I don't recall there being an exhaustion indicator in the bottom right. They didn't have any medical conditions or injuries that could cause them to collapse otherwise, so is this just a really rare mechanic I've never seen before?…
