Briefly going up for sale on Xbox Live yesterday, BioWare has pulled the Return to Ostagar downloadable content for Dragon Age: Origins until it can fix a title update that was breaking specialization classes.
A title update released yesterday meant to prepare the Xbox 360 version of Dragon Age: Origins for the Return to Ostagar DLC did more harm than good. Players began complaining that the specialization classes - subclasses of Dragon Age's four main character classes - were no longer functioning. In response, BioWare pulled the DLC, urging players not to download the title update in a post on the official game forums.
This morning a title update on the Xbox 360 for Dragon Age: Origins was made available in preparation for the release of Return to Ostagar. This title update introduced a previously undetected issue that causes specialization classes to not work correctly in Dragon Age: Origins. We are removing Return to Ostagar from Xbox Live until the issue is resolved and are recommending that you do not download the title update. If you have already performed the update, we apologize for this and are working hard to ensure a fix is available as soon as possible.
We will provide more information to you when it is available.
The downloadable content was previously delayed due to unforseen bugs. Yesterday's release for the Xbox 360 marked the first platform to get the new downloadable content, with PC and PlayStation 3 owners waiting impatiently for news on a release for their platform of choice.
