Me and a buddy found some broken geometry we could fly up though and it led to a hole in the map that lets you escape the playable area, could also maybe be used with some movement stuff to get to areas we shouldn't be able to but I'm not sure, if you tried to land near the hole but not go into it you tend to slide and fall through. Location: Nessus, Well of flame - go through a portal to yellow crystal thing, (photo two) then walk to the far, dark corner, the exact location is displayed on my map (photo one), then jump and you will clip out of the map https://imgur.com/a/e8ytsH8
