Have completely cleared the first level of the Hedvig's Laundry Room including all hidden rooms, but inadvertently left one pipe on the West side of the piping system that I already completed and turned the valve. Now there is no way to remove pipe sections from that pipe and no way to move the lone pipe section left inside the West side of this level and get it to the East side to repair that section of pipe and turn the valve. I can already see that there is a "hidden" tile inside the room that will eventually open when the East valve is turned, but there is no way for me to get there. I have searched the Wiki, the Forum, You Tube, and Google to no avail. I have submitted trouble tickets three times with no response. I can go no further in the game and am asking for anyone's assistance in clearing this glitch. I'll gladly send a screen shot that shows what I'm talking about, if you'd like to provide an email address. PLEASE HELP!
