Playing version 0.1.2 on Windows I ran into a weird counting bug when my food hit 500 because I was gaining food (from beehives) but when I hit 500 it decided I was in debt for 15 (or so) food each turn and I had to build even more beehives to get back out of debt! (It might have been the Slaughter card that caused me to go over 500... don't exactly remember).
