Found a bug (?). Once I entered dungeon 4 the screen goes dark, the music plays, it auto saves and that's it. I can't go to menu and had to exit game to restart it(clicking the auto save file, the screen was still dark). I tried going another day and time, but it still was dark. It occurred after i got defeated with Nora. (so I went inside the dungeon with Nora, fought the mobs, got defeated, started to grind to waste them, prepared to go again with Nora and when I entered... just darkness and music.)
Similar thing in gallery scenes (once it's over it's completed darkness).
