So. I was making my way through the Faron Temple in TLOZ: EOW, and I was having a hard time with finding the keys to the doors. Sometime later, I looked at the map. I needed the boss key and that was it. So when I looked for the only remaining treasure chest, it was behind a locked door. I had no keys. I quadruple checked the area, and there were no more keys. I fell into a flaw in the game. And since I’m that person who doesn’t manual save, I had to reload the game to before going back to Hyrule Castle and do it again. Just a warning to be careful.
