I was getting so upset with my nature tribe they wouldn't fish, chief was always getting pregnant, they wouldn't research, they wouldn't even repair the first hut without me making them, I was actually sent a barrell of kids because their wouldn't procreate! So I decided I would let them die. I came back days later with two huts built and all leaves cleared away. They did better without me, needless to say I was angry

then I felt bad because Chief had died along with all but one of the original villagers. I now have every female possible pregnant to revive the tribe.
Never give up on your tribe, they might outsmart you in the end. I actually may make a fic out of this.
