I've only had the game for 2 days. My 1st tribe died, ran out of food. For the life of me, I can't get anyone to unblock the stream. I read about Level 2 of 'construction', or whatever. I place builders there (adept), all they get is confused, with an undernote that more research is needed. So I take them to the research, and all they do is shake their heads. There is nothing left to farm (gather), the berries are gone, so they walk around exercising, do a rain dance or constantly wanting to water the strange field or try to push the boulder that's hiding something. It's getting very frustrating for me because I haven't a clue what to do. Can someone PLEASE help?
