While I get the buzzsaw is funny to kill stupid players who touch it, it aint so funny when settlers who do not know better keep running into it. That buzzsaw has killed like four settlers so far. They keep pathing or it for some reason. I put up some of the security cage walls around the plot and they still kept running into it and dying. The negative modifers for heaving dead settlers is just stagnating the settlement and it just will not grow due to the happiness.
