I think I'm stuck as I've studied the guides and previously posted forum messages. I have two master builders and just need one more. I had two adept builders repairing the huts over and over to no avail. Dam done, thorns done, two huts done, crops done. Population of 16.

I also can't upgrade levels because it takes so long to build up tech points even when I have the kids get all the stuff. So I'm stuck in that no one will become an elder (they're close) and that I don't have enough tech points to get the things I need to progress.
