I can't seem to get my new farm to get any moisture. I tried 1 water with 8 surrounding farm plots, then i tried to do a strip of water and farm plots beside it, then i tried to 1 plot with water on all side and i get nothing. There is nothing overhead at all. I have tried to restart several times. I was able to get 75% on a farm plot next to an existing pond about 40 squares away. What's the deal?
