Upon downloading dragonborn and downloading the patch, I decided to pick skyrim back up and make a new redguard warrior character. Everything was running smoothly (except a little long on the loading screens sometimes) until I got into bleak falls barrow. Upon ventureing through the dungeon, I found that I could not rotate the "key" pillars to delve deeper, they simply wouldn't respond. My friend has had the same problems with his game. He is unable to rotate "key" pillars, word walls will not give him new words, dragons often (but not always) fail to give him a soul, and several times he was unable to access the boat to solsthiem without reloading his file several times over.

Try clearing your console cache then restart the game.
