Having the same problem. I asked my friend on what to do and he said that I should finish all my introductory quests (and unlock the forge ?). I'm still on the process of doing these so I don't know if that's actually what we have to do.

I am also having the same problem. Bought Forsaken for the Last Word handcannon, and can't pickup the quest from the Drifter. Has anyone figured this out yet?
