Dragon Age : Origins' Return to Ostagar Pulled from XBOX Live

Dragon Age : Origins' Return to Ostagar DLC released on XBOX Live yesterday has been pulled from Live due to compatibility issues with a recently released title update for the game.  Issues are currently being resolved.  Here is the official statement;

“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,” Community Manager Chris Priestly explains. “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.”

There was no mention regarding if and/or how this afffects the DLC on the PlayStation 3 and PC versions.
