I did notice something else I never took notice before, so either I have been missing it all these years or its a new scene ...........
Right after you board your doom-buggy and the lap-bar closes , I think there a new scene BEFORE the library, and before the downward slope with the paintings on the right that change with the lightning effects.
There is a statue/bust on the left side, with a large staircase that starts at statue/bust on the left side and rises to above the doom-buggy path. There is a floating candelabra above the top of the staircase landing.
This is literally the FIRST scene you see as the doom-buggy leaves the loading area ............why don't I ever remember seeing this .........is it new ?
