Anyone know what is needed to trigger the third hut? I have 2 huts at max population and seem to be stuck. I can't do any more puzzles because I don't have the right god powers. But, I can't get more energy because I need to increase my population (which I can't without another hut). I am slowly converting blue heathens but they are all surrounded by red and yellow ones so it is hard to get them alone. Help!
