I’m relatively new to this game and me and my friend often play Black Forest together. We’ve encountered a problem where someone sends a villager to us at the beginning of the game and then builds walls and houses around themselves. I tried to stop them with militia but they were able to heal their walls and houses. Even when I rushed knights, I couldn’t reach the villager. We were both very frustrated because we spent so much resources trying to get rid of the villager and couldn’t do it.
