So I have been trying to get this for a while, even if in the same game, but different saves.
First I tried going vampire in all the holds, when that didnt work I tried going werewolf in all the holds, even made sure to see if I had the option to say: I am the thane line so it wouldnt make problems (read it online that being a thane can make unlocking this achievment problematic).
Still it wont unlock.
Anyone else had any experience on this here on gog? Is it normal or am I just unlucky?

Lol, I cant believe it, it unlocked yesterday, but I could have sworn I didnt see it unlock. :D Thanks for reading anyway guys.
