As BioWare explains: "This patch will fix the recent crashing that was caused by the upgrade to the 3.3 firmware update. It will also fix the in-game DLC store to show free DLC content redeemed with promo codes and it will also fix the bug with Darkspawn Trophies."
The Dragon Age: Origins 'Darkspawn Chronicles' download pack was released earlier this week, and has you fight as the Darkspawn, put in command of genlocks, hurlocks, shrieks, and ogres in an alternative history.
