It MUST be removed, because there we see CHIEF BAST alive. He is who tells Tarkin that is a little danger to the station and ask him if they must prepare his shuttle. Tarkin answer NO, and we can assume he dies in Death Star.
But in the HS the Chief Bast is walking with Vader when the sith Lord is informed about a Corellian Vessel going to Kashyyk (I always have trouble with this name!!!!)
