I found a complete and utter game-breaking bug. I'm 28 hours in and now I've lost everything.
I was in the modern-city version of what used to be my home. I went into the E-library and stumbled upon the cut-scene with the long story. I had seen it already and didn't want to sit through it again, so I hit F-6 during the story.
From that point on, the game restarted on me, except I had all my medals and all my triforce pieces, and all my equipment. Except I was back at the beginning, back in the original times before the apocalypse. I think, sadly, that's it for me. I'm done.
That happened to me too. I was able to revert because I hadn't saved in awhile. I lost a bit of progress but was able to keep playing.
