A new patch is out for Dragon Age II, bringing with it numerous gameplay bug and quest fixes.
Note if you are suffering plot bugs, you "may need to revert to an earlier save, particularly a save prior to visiting the affected area during the current year in the game."
Performance and DirectX 11 issues should also be resolved, though you must be on the latest video drivers to ensure.
We haven't heard anything about a console update, but we'll be sure to let you know if one hits.
