I got stuck right there behind the chest, where I followed the path and turned slightly left next to my charakter box and it seemed like I sunk in a hole. Right after that I couldnt move out.
Happaned in Iron Outpost on Legendary difficulty. I doubt that it has something to do with the difficulty, unless structure of the map changes accordingly wich difficulty I choose to make it.
Aaaanyway I got stuck, had to reaload game save to continue dungen.
If its not clear enough wich map layout it is, here another one. Thats all I can do since I cant move
