I always wonder how these make it past long winters without a freezer. But then I noticed you have meat drying racks. I wonder I that comes with a salt harvesting mechanic.
Also is there a mod to make flour from grains? As somthing to ensure other tribes are also limited to medieval tech. I fear If I took this challenge printer whould just pop in with some doomsday launchers and destroy me.
Vanilla Factions Expanded Classical has large passive coolers that actually reach freezing temperatures.
Medieval Overhaul has Wheat that makes Flour that can then be turned into bread.
As for limiting what can spawn I suggest turning off all factions besides those from Medieval Overhaul and Vanilla Factions Expanded Medieval. And also using the storyteller from Vanilla Factions Expanded Medieval.
