I remember when Broken Steel came out - the only major bug in that DLC was directly because of the fact that it was only tested on completed save files. If you start a new game, the news would talk about things that hadn't happened yet.
This bug was directly because the patch was only tested on Xbox 360's that already had the upcoming DLC loaded onto them. They didn't consider how a typical user would get this patch.
