I played the game until I had solved all but the GC and boulder puzzles, had plenty of food, 65 villagers, all techs maxed out, but had to deal with the zonbie waterers for the last few days. The crops did NOT replenish. I directed the farmers to plant, and they did, but still the crops did not return. Luckily, I had enough fish and crabs to last forever. Then the game totally crashed and is unplayable. I wonder if this is a bug?
