I recently just bought a Manaan Retreat Stronghold, just because it looked nice, and I found that midway through the Entrance Plaza, on the left-hand side heading inside (right-hand side coming outside), one of the hooks is missing. Wondering if anyone else has this problem and how it can be fixed.

Currently, I have finished story missions up to A Traitor Among The Chiss, but as I finished them before the Nathema Conspiracy came out, I can't get the story mission for Nathema. Any help?
