I did all the deadric quests and got all the artifacts. No trophy. This stinks. Do you know what might have caused it? And I promise I did not glitch or anything, and made sure all of them are an actual deadric artifact
How can you know for sure it didn’t glitch? Because there is a glitch related to the achievement, not sure if it was ever fixed or not. But if it didn’t then check this list here and make sure you have the right daedric artifacts. Not all of them count towards the achievement, like e.g. the skeleton key!
