I have browsed all of the google hoping to find an answer to my problem. I am in Skuldafn Temple, and I'm having the same problem others seem to have had with the ring puzzle door.
Initially, the rings wouldn't move at all. I went back one loading screen and returned to fix it. Now, the pattern is correct, but the key does not open the door.
- I have exited the entire dungeon and re-entered
- I have made sure the left (unnecessary) door/gate is closed on the first pillar puzzle.
- I have saved and reloaded.
- I have gone to the Xbox dash, powered off, etc, the console.
- I have tried several erroneous arrangements.
- I have cleared my cache, some old saves, and the system cache.
And I'm unable to climb the mountain. I tried for a half hour, and after making no progress I gave up.
