I made that a very long time ago, its inacurate and the DL is gone :p.
But I am working on a new map now (Small but sexy).
The thing is, the ladders are bugging (They finnaly lay down as they should, but when they are up you can walk *on* them)
Please help if you notice this comment and you know the answer :p.
