I've been playing through as an Imperial Agent and have been going through Nar Shaddaa's story. I got to the quest Wiping the Slate, but when I got to the end the game bugged and led me to take the elevator at the end. After I took the elevator, the map marked terminal back where I just was, but I couldn't get back through the elevator or through the way I originally went. I was completely locked out of the area, so I abandoned the quest thinking I could just go pick it up again. I was given no warning that the quest couldn't be reacquired. Problem is, I got back to the Major who gives the quest, and he won't give it to me. When I try speaking to him, I see a cut scene of a close-up of what I think is a holocom, he tells me to go away, and the cutscene ends.
How do I get this quest back to finish the Nar Shaddaa story?
