So, I used a map which was shared in a guide made by Flissa (Discovery Locations, Obelisks, Interactable NPCs, Emotes, Exclusive Recipes, The Exiles Journey:) and marked everything I already explored with a red circle.
Can anybody tell me which locations I am missing? Eighter I am blind OR there are PoI’s out there which are missing on said/every map?
Or is it simply the step being broken and never counting? 
EDIT:
There 2 comments are:
Author of guide: “non” is South-West of the map, well past the Soul Wall and can only be reached by teleporting.
Comment: i downloaded the “all map markers” mod and got X-8 with the only missing location being “non”. wherever that is. maybe the modauther could help with the necessary locations (list) for this mod.
