Unable to get to second part of map (Atlas maps)

Bug Report ID: #2700705337

Started a map and cleared some mobs. Noticed that I can see mobs and a second part, also can see on Map, but unable to get there. No switches or portals opened to get to second part. No boss defeated yet, killed all mobs on this part of map.
