This is driving me crazy. I've been able to do the shrine quests for valor, sacrifice, justice, honor, and compassion just fine, but when I go to do the quest for the shrine of humility, I go to the Codex and read the book, then return to the shrine, but nothing happens. It doesn't say well done or advance it or anything. This is not good, because it's quest required to win the game. Any ideas?

Ok. I figured it out. Apparently when you get the shrine quest from humility, it flags it as being from the shrine of spirituality, so when you go to the Codex it shows you the spirituality page. Then, if you go to the shrine of spirituality it will complete the quest. Then, when you go back to the shrine of humility, it properly flags as the shrine of humility quest, and you can go to the Codex and back to complete it as normal.
