I'm hitting this too. It says 42 apples per minute, but it's taking out 78 apples every 10 seconds. I kinda don't mind if it's supposed to be 42/min or supposed to be 468/min, but right now it's tricky to just a guess on how much to supply. (running 0.2.1 but with older save game, not sure if that matters).
Heya! We had a couple more bugs, but with the latest 0.3.x it should be consuming what the town hall says every minute.
