Where is the 4th one? I've even unlocked the camera rotation to search that room in 360 degrees and cannot find it.
I found two in the top left of the room that are pretty close to each other. They are on the corners of the wall. The third one that I found was hidden behind a tall candleholder.
At this point, I'm starting to wonder if I ran into (another) glitch. I've spent over an hour in this room and just want to move on with the game. While you may think it I've overly exaggerated my time... either my watch is running a lot faster then normal, or I'm just being too patient with this puzzle.
