You can make adjustments yourself after loading this scenario.

i dont know about vents being disabled, its not electrical at all and pretty sure in the old times ventilation was still a thing

Let me tell you, the medieval mod I think is more challenging than the base game. I don't think I'll disable it in this scenario, but I recommend people consider disabling heat waves. They happen almost constantly, and you will have people passing out from heatstroke. The negative mood just from being hot... sleeping in the heat... it's just ridiculous. You end up spending HUNDREDS of wood every 5 days on passive coolers.

Thanks, I was looking for something like this because I never got around to doing it myself.
