My crops just failed for the first time and my saved food stocks are dropping like the proverbial stone. I have 12 villagers right now. I'd put four on breeding duty earlier in the day thus 8 are adults, four are kids. I'm 30k of the way towards my next tech which I'd planned to be harvesting. What exactly are the cycles that the crops and berries follow? I've yet to see the berry bush regenerate save for when the drum is played.
