Bug Found at WP in Forest

Found a bug either with the map or with a entrance to a zone. The particular gate way is the gate way from Merveil Lair to the forest. When you get into the forest from Merveil's lair the map shows (with the orange area) that you can seem to go back into the lair, in my case it was to get the rest of my loot. To me if this is not the case it seems confusing to the player that the area is "orange" and you should be able to return without running from the Waypoint all the way back to the boss room.

These are images of the the area. The first image is with the full map, and the second image is with the "mini map".
