My first tribe was very unlucky. I ended up playing it for like six hours straight to collect mushrooms just so they wouldn't starve. (I didn't think about putting the game on pause for whatever reason.) The collectibles were also a pain in the tush 'cause they didn't show up at all really and when they did they were repeats.
My second tribe is brilliant! No problems there what-so-ever. Although I had two kids who turned 14 train themselves as farmers while I was gone and one of them didn't like crab meat or mangos and the other didn't like fish.
I was low on farmers so I had to fix it.
Other than that no problems.
