I can't get the characters to reproduce. Made both women and all men parents.Tney embrace, go into the love shack but nothing happens. I have 3 shacks built so that's not the problem. Have plenty of food so they're not worried about it. I spent 15 minutes dropping guys on girls constantly - must have been over 100. They had quite a party but no babies.

I'm concerned that my original group is getting old, I only have 1 child left to collect items and there's no new generation. I only have 11 people and some are nearing 60 so time is critical.
