Lol on the door, like I said use just a little logic on it and the answer will come to you....

Attachments aren't working but the one I found so far is a small book case near the door in the building with lots of book cases. It looks like its a "prop_static" meaning it doesn't move, I just checked and that's how it is in the original. Now its fixed, if that's the one your talking about. Is the ledge in any of my screenshots?

The extra prop in the cage area is done, I would like to see how it plays, things can always be tweaked later.

Thanks
