PDB Act 2 - DON'T PLAY ON ITS OWN!

Something strange happened when i tried gettin out of basement (i went to some secret zone of sorts and the sky was red)

Im stuck at the bit where you look for mr. Blind

Im stuck.The library with the fireplace has disappeared and is just a wall. I did a side comparison with someones yt play thru video and theirs is there. I went in before but now its gone.I only have 2 clues left and keys i cant get and unusable items now
