I can't determine if I just made a mistake at some point in playing, or if I'm just really bad at this game, but I need some help. I'm on my first game that has lasted successfully for any amount of time (on the others I left the speed on Fast and forgot to check it for a day or two at a time, so all my villagers died). My problem is that I can't get my food store up to an acceptable level. I have 2-3 people either harvesting or foraging at any given time, yet right now for instance my food level is below 100. Is there anything I can do to get this situation flowing in a positive direction?
