I've seem to have ran into a problem. I completed the 'Elder Knowledge' quest (infact I completed the main quest) but no trophy was given. How do I get the trophy now?. Created by ajvizz. games-recreation-en - video-online-games-en

Unless you're certain it's all done, it seems unlikely you'll be able to get it, unless there is another patch incoming and this is a known glitch. It seems the only other thing you can try is reloading a save before that point (assuming you have used multiple saves that is) or restart the game.
