I’ve run into the same issue...from what I understand it is because at one point you deleted a quest , so now the game is glitched and more won’t drop. One of the forums mentioned loading another character, then getting a badge on them, and then switching back. I just found that out last night, so I am not sure if it works. However, I did have a badge drop in the first 5 minutes on my other character, so at least the glitch is character dependent.
