Visited Raldbthar a 2nd time to confirm a bug I was told. On the lower level of Raldbthar there are cogwheels which had to be unstuck when I first visited the place. Now the dungeon was reset, enemies respawned, treasure chests and the like are filled again and the wheels are stuck once more, yet there is nothing I can do. The things that blocked them at first are still lying on the ground. This pretty much prevents me from researching that odd machine right at the end of the dungeon, as I cannot enter the place from the exit/rear entrance either.
