Hi, I did the slate thing that organized the heat so I could turn the red and blue switches.(after turning all the door switches to the right) The Bahro came, did it's thing and yes there was blue steam, the buttons popped up for the swtiches, I was about to walk over to sort that puzzle out when I was called away. When I got back, buttons have all popped down again, slate gone! I looked on the pedestal, I went back to the start (ladder) and looked on that pedestal nothing! Where is my slate? It's not on the floor where the Bahro left it, I can't find it anywhere. Do I have to go back and start all over again? If so, how do I get back into the ice tunnel? it's blocked.

Hi again, All ok, I forgot about linking back from the pedestal, did that, retrieved my slate from the bubble. Back on track now, just thought I would leave this post here to warn people about leaving the game for more than a few minutes without saving.
