I went to bed last night and 3 outs of 6 people died. When I woke up the others died shortly later. The berry bush ran out while I slept and I didn't have the chance to advance to farming.

Can anyone give me some advice to keep the villagers from starving to death over night each time I start the game.

pause the game until you wake up again

or if you are unwilling to do that, make sure the game is on half time

and make sure you only have one maybe 2 farmers and everyone else on research... and someone should knwo how to heal
