Alright guys, I appreciate the help but please do note the following.
- As the screenshots show, there is no picture in the room for me.
- I have already pulled the lever.
It looks like you have run into a bug here... Do you have a save right before you entered the Black Cove (I know, losing a few hours of progress is irksome!)? Try verifying your game local files via Steam client and load the save game before the Black Cove. Hopefully, the bug will be gone then! If it does not help, you should maybe reinstall the game completely (you can keep your save games).
