I have a town that was doing just fine for hours today. I just closed it out of frustration, but I was year 50 for sure. I had a population of 350 and was doing fine. I had a bit of a food problem, but I was staying steady at ~700 left in stock and it was growing. But then all of the sudden after I built my market, everybody in the vicinity of it began to starve. And then they began to starve at an even greater radius. And before I know it, I'm down to 280 citizens.

Any idea what caused that? Is there some glitch I'm missing? I had starving villagers walking into their homes while starving, and sitting there in a house that was stocked with firewood but no food. And when I look at the market (with 8/12 vendors), it's full of food. What's going on?
