You've already talked to your priest/ess to access the Madrana quest, right? Can you try it now and see if it works?
Yeah, and still hasn't.
Input this on the game codes in the main menu: Madrana
Should force restart and allow you access!
Sorry for the late reply, but you're talking about the special game code option in the shrine, right? I've tried typing "Madrana" there, but says that it's the wrong code. I tried clicking travel to Madrana, but still the same outcome as usual.
