Whether fortunately or unfortunately, this time the issue is something players have seen before and have devised workarounds against. The "copying add-ons" glitch is less of a game-breaking bug and more of an annoyance—forcing players to wait up to nearly half an hour just to log on to their account.
Here's a few fixes we've found to make things run a bit smoother while Raven Software comes up with a patch.

How to Fix Warzone Copying Add-Ons Glitch
Essentially, this glitch just forces the game to copy all the player's additional content every time they start-up the game. This can be irritating and downright detrimental to players as not only does it cut into their gaming time, it also carries a chance to buffer indefinitely.
The best way to fix this is to re-install your Campaign Packs and Campaign/Special Ops Compatibility Pack. While this does take up more space on your device, it will stop the game from redownloading content upon every start-up—eliminating the glitch. Each pack should be around 1 MB each.
Other fixes include a full re-install of the game software and removing the software disc, cleaning it thoroughly, and replacing it in the device. However, these are known to be circumstantial and less effective.
It should be noted that this issue only seems to affect disc-users. Digital download players either aren't bothered by this or have it appear at a significantly less frequent rate.
