As you can see in this image of the map just below the compass there is a marking line used in development this is the same on the full Gundabad map apart from it is red and even can be seen on the map housing items.
This could be fixed along with adding the zone text for Elderslade,The Pit of Stonejaws and Welkin-lofts
Also another map error is on the stable masters map Ost Guruth is in its correct place in Lone-lands instead it is floating above near the North Downs and Wildwood isnt included on the Bree map portion
