Turn 370, most of the factions are pillaged to the ground. All I can do is to capture barbarian settlements (to unlock them as playable faction) and then encamp/dig some military unit there to keep the settlement from switching back.
This is all good enough for me (I see this game still as an alpha version).
But what about enemy pillaged farms, mines, etc.? Is there any way to capture them?
Unpillaged farms can be captured, abandoned and enemy clans killed, but the pillaged ones are just sitting there, holding territory, blocking resources.

I would like to get rid of them - no need for capture, just one button "Burn them to the ground" which would delete the farm and clan from the game.
