In Shiraki Temple, i needed to activate the air shrine, and when I entered the room, there was nobody there to defeat, and when I walked up to the shrine It wouldn't let me press X. After that I left the room atleast 5 times, went far away from it, tried again, and it did the SAME thing... So I had to exit Mooshu, and now i probably have to start over again in that whole dugeon that already took me an Hour and 1/2. And NO, I didn't already defeat the people in there, and forgot about it...
