Patch Update! So the Downloading of all maps again is due to a change in the Key system for DLC. You don't actually re-download the whole map just a tiny little key update. Should be really fast. Sorry Microsoft doesn't have very good messaging for this. As for the loss of Spec Ops stats I'm looking into it. I'm really pissed that that might be broken so am angrily finding out what went wrong. I'll update you all asap.
