One more, seemingly trivial question: have you unlocked the sector yet at all? If not, you may need to play 'Drukhari Menace' if you haven't yet, that should unlock the sector. You can access it by scrolling through the tabs of the current objective window in the upper right corner of your screen. 

I've fixed a couple issues with some of your characters, but I couldn't find anything wrong with your lvl 81 character. Could you maybe try looking for missions on the mission deployment screen? Which you can open with L2 from the starmap or command bridge. Cheers

hey, could you please share with me your account name? I'll take a look if there is anything stuck.
