ok I was going for the oblivion walker achievement , I have completed all the daedric quests ,

my log says 15 deadric quests complete

I have 1 azuras star, 2 Dawnbreaker, 3 Ebony blade, 4 Ebony mail, 5 Mace of molag bal ,6 Masque of Clavicus vile,7 Mehrunes razor, 8 Oghma infinium, 9 Sanguines rose, 10 Skull of corruption,

11 spellbreaker,12 saviors hide, 13 ring of namira,14 wabbajack, and 15 Volendrung in my inventory

and the achievement didn't pop for me. the last quest I did was boethiahs calling

I have a manual save just outside the mine before I completed boethias calling

so any ideas? cuz its one of only 2 achievs I got left and I really want to check it off ive read some ppl say you need 16 but only way to do that is with the ill met by moonlight quest glitch to get the hide and the ring

any help would be greatly appreciated

Should have gotten the Ring of Hircine first, then the Savior's Hide.
