In mission, So Foul and Faraday, I take Sally to the home of Nick Lightbearer to find the unicorn song for Dr. Faraday. I got upstairs, turned the guitars correctly, and used button in back of mirror to reveal the entrance to Nicks hideout. Follow the prompt to enter the hideout, screen goes black for a couple seconds, but dosen't take me anywhere. brings me right back to the room upstairs with the mirror, and guitars. Thus, hindering any further progression in the game whatsoever. If it helps, i used the button behind the mirror once or twice before i realized that the guitars needed to be turned correctly first. This is on PS4, build v1.8.85815. Looking forward to your assistance! Thanks in advance!
