In the service elevator, on the lobby level, take the elevator to the bilge level and the green light that indicates the elevator level will go all the way to the bottom even though the elevator doesn't.
The original interpreter has it go down about 70%. The elevator goes to the correct place.

If you click to go to the bottom level it resets the level to where the bilge should of been and looks good from there.

If you turn around and turn back the elevator shows the correct position for the bilge room.

If you go to the bottom and then go back to the bilge room it also shows the right position.
