When i cross in a plane or tank to my no2 sim the camera becomes altered. Sometimes i can no longer control the "machine" and end up in the SW corner under water. I have already removed about 20 "invisible" small triangles along the northern border - obviously griefing - but i still have a problem which makes my sim "polecat" unpleasant and unusable. I am therefore paying for what I do not get and also denying more space to my flying / fighting friends. I have had the griefing exorcists for many hours trying to help - but apart from the "triangles" I am still unable to use my sim. Help please soon - its a sorry site / sight :(
