I had crops growing for a while and now they won't reappear. I have level 2 on everything now and my population has dwindled from 11 down to 6. Nobody has died from starvation exactly, but I think they did die from malnutrition. (living on foraged food, not crops) I've never had this problem before, at least for as long as I've had it now. Has anyone ever heard of this?
