I went to do a quest on the dreadnaught and all the story missions were available again. I couldn't do anything except the story mission and so I went and boarded the cabal ship and did that mission. I finished it and traveled back to the dreadnaught and now it's available again. I traveled to the entrance of the dreadnaught and the first quest was forced on me again. How do I travel to a location without it making me do that quest. This is starting to annoy me now. Thanks in advance
