I completed the Laso playlist for Halo 3 four days ago and still havent gotten the achievement for steam however still i recieved it through the xbox ahievements and got the nameplate. I believe this is the only ahievement that hasn’t gone through for me asi i recieved all my Par’s and the no pain no gain ahievements.
Yeah, I’m missing it too after already having the achievement on Xbox. Missing the Aficiando (which I don’t think is a word; Aficionado is) achievement as well.
