I feel like this is not so much a bug as just a fact of living in medieval times. They drank more booze than water. I say they should keep the ale consumption as is and just make it easier to grow hops. I want my villagers sloshed to the gills in historically accurate fashion god dammit.
I’m told that’s a lies my teacher told me thing, and folks did drink water from wells and whatnbot that were known to be safe.
