No Walls for Minor Settlements
Another mod from my personal collection to flavour your campaign the way you want it.
This removes walls from defence structure upgrades for minor settlements and will result in more field battles and less siege battles.
It is adviced to use a garrison mod with this. I use Trebor’s Garrison Overhaul myself. It is also adviced to use a campaign AI mod that will build more defence structure upgrades to minor settlements.
