Yes, I think you know the bug, but for those who don't know, let me state it again.
"I got all the Daedric Artifacts (Skeleton Key is an exemption) and I haven't got the "Oblivion Walker" achievement. What should I do?"
So, in my case. I got almost all the daedric artifacts (15 of 'em) LEGITIMATELY (except that I used console commands for the Skull of Corruption because I'm a good girl [my character is a female] and I don't want to make the people suffer from their nightmares.) and I haven't got the Spellbreaker yet. Hmmm, I still don't have the achievement.
Does the console command affects quest achievements? If it does, what should I do to undo or redo it? What if I'll obtain the Spellbreaker, will the achievement trigger?
Thanks in advance and cheers! :)
P.S. - I'm KINDA new to TESV: Skyrim and I do need some good help for this one. Hehe.
