I've played Civ4 on my PC about 5 times now, and I've got all the basics down while playing on Noble. However can someone please tell me why my cities won't grow, even though it says 20 of 15 next to my food meter. I've looked everywhere in the game to try to figure this out but there is no explanation to why this happens. I have farms, more than enough to grow my population, but my food growth meter still says "0". And no there is no anarchy. Everything else is growing and moving along just fine in the city, but every now and then a city or two will stop growing for no reason for anywhere from 2 to 20 turns. Obviously this greatly slows down my cities' growth and I fall behind the other civs. This usually happens more in the early stages of the game when population is below 10. Am I discouraging growth to my citizens somehow that isn't explained in the rule book (which I have scoured for this problem)? Any help is greatly appreciated! Thanks!
