The Drunken house of a baron

[Stubag]

There is a room in the end of the corridor with an open door. Go in there. Then you see boxes in front of the wall. move them aside and continue.

you know that i said "i already got the key" so i know that I need to pass that boxes to reach the room but the door in there won't open with the machine key and the door at the end won't open too

The key should work and this my proof but I will check later if there is really some bug.
