I'm getting hit with plagues every month. Losing 1/4 to 1/3 of my entire population every month. At this point I have a Physician, an Apothecary, and a Water Supply on every block, two or three on big blocks. I produce or import about three times the amount of food I consume, five types, well, I guess flax isn't food exactly. The overlays show everything to be just about perfect when my population caps out around 6200, still good when I take a loss from plague. Maintaining about 4% unemployment, lots of shrines and temples around. I've got Health and sanitation as my only priority. All I've been able to figure out is that if I can catch the plague right as it's starting, and remove all of the housing for a block or two, it won't spread. However, it occurs to me that it takes just as long to repopulate that way as just waiting out the plague. How do I turn off the plagues?
I've also noticed that housing areas will say they don't have access to something when they're right next door or accross the road from it. What's that about? They can't cross the street to save their lives (literally), but they can walk all the way accross town to go to work?
