On my map I have a weird square icon that is red with a little flag in it and it says its a Player Marker. It's completely seperate to the purple marker that I can place on, and move or delete from the map - doing this stuff does not effect the red marker at all. Its positioned at an Ayleid Well just south-southwest of Fort Roebuck.
I don't know why its there or where it came from. I do have quite a few mods running. Has anyone else had this or know why its on the map - and more importantly how can i get rid of it, it's really annoying me!
