Title: Able to access the roof and the "inside" of the Archon's Keep and environment around it. Platform: PlayStation 4 (maybe others but i don't own them. Description: After random PVE exploration, i accidentally found this bug. It is a 100% reproduction rate (after 8 attempts). As you can see in the video, i am able to walk around in the usually inaccessible "rooms" outside of the proper gamespace, as well as falling onto the ends of mountain polygons and exploring blank flatness. You can even fall into the cave system past the Archon's Forge. Steps to reproduce: 1.Launch "Patrol the Plaguelands" 2.Proceed to the Archon's Keep and follow the exterior left wall from the entrance and follow my jumping in the video 2. On top of the roof, move to the left and you should see an empty space which you can jump into. Just explore there.
