I’m not saying what happened to it, I’m asking what happened to it.
It is laying on the robe as Vader stomps on it.
After that point, following the Falcon’s escape, unknown.
Actually, no one knows what goes on behind those closed blast doors. Or why Vader initially walks the other way, like he is asking the stormtroopers to join him into battle against a farmboy, a prince, smuggler, and a wookie.
