Leoric Ghostly Death Scene Before Boss Glitch

The scene where Leoric is in the center of the room with what appear to be guards is triggered to begin playing if you ran through it. I ran past it to the pots to the left and right of it, ashes rather, and then moved forward and spotted Leoric there where he enables the skeletons spawners. I ran back into the prior area where the scene occurs, and ran into the center to trigger the scene, and nothing happened, everyone just stood there instead. I believe they should of disappeared, but it'd probably be easiest to just make the scene trigger the moment you enter the room.
