Skyrim storage help please?

So i know a lot of people out there have used a mannequin item duplication glitch in the game so i decided to see what i could do with my house in Riften because I want another set of nightingale armor. When i tried it both mannequins came off of their stands, one is pushed between the standing the corner and the other is attached to the ceiling by its head across the room (cant get the pic i took on here though :/ ) and both mannequins are unequipped. So what happened? Is the glitch still working or did i F### something up
