I'm playing the Steam version of the game. I collected the 3 scraps of paper however when I use the numbers from the 3 papers on the combination lock it just says "No, it's not that..." and the door remains locked. Any other combination has a different response with it saying "I was sure it was that... Unless?" Is there something I'm missing? I can't find anything else to interact with. (Edit: I got it the middle note is supposed to be upside down. However it looks like the messages for the codes are mixed.)
