I managed to get back into the glitch on this map, yesterday, and grab some screenshots to show where it is.
I am calling it a glitch because, whilst it wasn't fully checked out, one can certainly kill other players unseen
from it and it obviously isn't somewhere the mapmaker intended players to go. I suggest Admins warn anyone
located in it to move from it.
As per my previous message on this topic, some time ago, the glitch is in the attic of the first building on the left
at the end of the big bridge. To enter it, one has to go to the next building along (accessed via the alleyway at
the rear) then ascend the stairs to a room with a small window overlooking the bridge. There's an open book
on the windowsill. Climb into the window opening then jump towards the roof opposite - you go through it into
the glitch.
