Warning: spoilers


I'm stuck in chapter 6, towards the end, I was replaying the chapter for the final achievement and I encountered an invisible wall on the flight of stairs just before the throne diorama, see picture. Can't progress, even from a fresh savefile (I tried replaying the single chapter, loading an autosave, starting anew from the beginning, to no avail).

Hey! I know this is a bit old but I just had this exact same bug, what I did was save just in front of that stairs (do it in a different slot jic) and load that save, while the game is loading I just spammed W to try to walk in that direction and somehow it worked, I was at the end of that flight of stairs when the game was fully loaded!

Hope it helps someone.
