After not getting this when I unlocked it I researched and found that this achievement has been bugged for everyone since November. I am extremely frustrated that I spent the time to unlock it and it is broken. I have cancelled my ESO Plus subscription for now until this is fixed. I don't want to keep paying for something that has zero support. I was hoping it would have been fixed with the release of Greymoor but I guess not. Also, the "time played" stat that tracks your time has been broken for months too. Once these two things are fixed I will reconsider resubscribing.
