With this little update i just focalized more on respawn, above all for infected.
With the last change of place for the unused room door, it gave me the opportunity to add a new "checkpoint" for infected.
Why? Well, when you are in the unused room, your objective as survivor is to break the wall, which brings you to the previous hall. In short, this means you have to kill all the infected you have in front of you. And, even if i consider this really cool, it would be impossible to go on, above all if you are the last survivor.
To help the infected, however, i added a new, but short, checkpoint in the hall.
How does it work? When the survivors press the button to open the room with stairs, a respawn point will appear, almost like at the beginning. For survivors, this will be really hard, but i think it could work.
So, at the end, the map has now 7 respawn points for Infected, plus a short one.

Also, with this update i fixed a problem in archieve room.
Update: AND added a hidden time limit for whoever stays in the lounge for more than 40 seconds after you opened the door for the elevator.
