I have a character that's been unplayable since January 7 because her class quest bugged out. I finished one leg of the quest, turned it in, got the reward, got the next leg of the questline, and then logged for the night. When I logged in the next day, the quest I'd already completed (and turned in and gotten XP and an item for!) was back in my quest log. So was the next step in the questline. They were both there, at the same time, and I had a holocom button on my screen saying I had a call. But when I hit the button, nothing happens but a single (audio) line from one of the quest givers.
I've been trying to get her fixed since January 7th. I've given up at this point. I can't advance her, and I can't complete the previous quest - I've tried multiple times, in different ways, etc. I can't abandon it. I'm stuck.
