I'm doing the Miscellaneous Quest "learn the word of power at Arcwind Point." So, I get past everything and end up in front of the word wall. Great. Everything's fine and dandy until I learn the word, and the quest doesn't end. The marker stays in front of the wall and won't go away. Normally, I wouldn't be too concerned except, with the quest still active, I can't go to High Hrothgar and find new locations for words. Any suggestions as to how to fix this?
