As the title says, I can't continue the Black Armory quest line as i can't accept the next mission. in the video I linked it shows that the conversation initiates and i have the right item, but i cannot click accept. Other quests have worked fine for me.
I'm having the exact same issue on my warlock. I have everything opened on my hunter so I decided to check my titan to see if maybe something was holding it up that way. My titan is on the quest for spider to go to the EDZ and check the caches. Every time I try to go in and do the quest, about half way in it kicks me back to orbit. So I can't even see if I can progress the quest line on my titan. I picked up some dailies from Ada1 and found out I can't even start the forge either. So it seems there's something with just all the forge quests in general.
