I can't seem to have children. My adult villagers 'go indoors', have their fun and come out empty handed! I only have one child left and she's getting older by the minute... any hints?
also, you don't need to actually wait till they go in and out the hut. just keep an eye on your population as you drop them on each other and when it increases you can pick up the female before she even enters the hut and you'll see that she'll have the offspring with her already...
