Ok so about an hour ago I wanted to make an underground dwelling for a change. After a few minutes of digging into a mountainside, I started to get notifications of Hearthlings being severely low health, I was really confused when this happened.
At first I thought it was because there wasn’t enough food, but the daily report said I had well over enough food for the whole colony, then I noticed it was the cramped environment debuff.
Even in a 11x11 room Hearthlings still feel cramped and start to lose health overtime, so I think the cramped environment should be less powerful or it should only lessen the mood of the Hearthling, not their actual health.
