I Found the Same [MISSING DATA] Room everyone here is also talking about. Here's how to get to it, Make sure to follow EXACTLY.
Once in the room without furniture, wait until the music stops completely before using the door upstairs, Once it stops, Use the door. Next head downstairs by JUMPING OVER THE RAILING of the stair case and head to the door behind the clock in the back on the right. It is important that the clock does not start chiming, jumping over the railing does not cause it to chime.
I also am making a series on this on my channel and the first video will be uploaded soon whenever I find time.
