I was playing EB today and i read the year in history notification that there was a plague in Rome this year, and it made me realize something... I haven't seen a plague in EB, ever. I've had cities go to 6, 12, 24,000 population with little more than simple drainage built, but have never, ever had a plague.

Nor have i ever seen an earthquake, nor have i ever seen or suffered from a storm at sea.

What gives? Have all those been taken out, or is it just a crazy coincidence that i've never ever seen any of them?
