In Iron vale on the map outside the mine there is a cog for an event called ’halt dredge mining expansion ’ .It shows that there is supposed to be a veteran dredge controller and a dredge drilling machine but there is never anything in the place where they should be.The health bars for both are permanently at 0 .I have stood in the place for 30 min waiting to see if the would spawn but they never appear.Is this a known issue?
