I hadn't had any of the disastrous events until recently. Now first you have to look at these stats (pic attached). The birth of my first set of triplets put my ranking to 666 - the "number of the beast" - a couple hours later the typhoon hit and wiped out ALL that food! I was really worried cuz I had 89 villagers and I was afraid they'd start starving, but it seems the crops are more bountiful when you have more mouths to feed cuz inside of an hour my food was back up to nearly 4,000.
