candid dagger
open vault
it is the blue room. I have gotten out of it before weeks ago and now all of a sudden it doesn't work. AND I didn't know there was a red room to the water treatment plant

If that is how you get out of the blue room, why put a switch at the door, or is that part of the puzzle? I don't think I had to do that last time I was in that room

In the room where you find the red card on the table there should be a switch on the wall, only when that is turned on will the button to let you out of the blue room work.
