I was helping a friend build a house and when I came back I found this structure around my living area. I built a wall around by home for a town and claimed just the wall and GrimNight went and built this structure inside the town walls and then proceeded to claim it so that I could not remove it. I also found more of these structures farther away from my home.
The general rule is that if it's isn't claimed in the first place, we can't do anything about it. From what you are telling me, you built a wall area but never claimed any of it. No action can be taken upon the reported player. Thread locked.
