Aren't there two doors by Voga? One of them cannot be opened (Must be cut content for I see rooms on my map) and the door with 2 guards outside it around the corner from Voga.

HK-47: "Expletive: Damn it, master, I am an assassination droid... not a dictionary!"
"Angry Statement: If I see one more meatbag attempt to attack a Jedi with a blaster pistol, I'll kill him myself!"
