Forum:KB:What happened to Vader's chest box?

Okay, immediately after Vader died in Return of the Jedi, Vader's chest box seemed to have disappeared (its especially noticeable when Luke is stroking his father's corpse's chest before breaking down). It can't simply have fallen off, as it is pretty much irreversibly connected to his diaphragm via that giant cable (A 3-D Reconstruction Log makes that pretty clear). Maybe I'm missing something, but how did it fall off? Was it a costuming mistake? Weedle McHairybug (talk) 03:38, July 8, 2013 (UTC)
