Update: The issue associated with the update causing data corruption has been resolved; you'll no longer encounter the error message, but the damage may have already been done temporarily. Infinity Ward says this is a one-time issue, so you're free to use them now. However, if you hit "yes" on the error message, certain stats, leaderboard rankings, and so on will have been wiped. Actual progression, like your profile and weapon ranks, has not been lost. If you have yet to download the update, you're now safe to do so. You shouldn't get the bug. Our original story continues below.

Since the release of the new Call of Duty: Modern Warfare patch, a few technical issues have arisen. Infinity Ward has provided an update for an ongoing issue that has, in some cases, wiped players' stats and reset other elements of the game. The new problems come just after the newest patch came out, featuring a new crossbow weapon and more. But, as of January 24, there's still no word on when the more significant of the two problems--stats seemingly being reset--will be fixed.

A fix was released not long after the update itself on January 22, and because this was a "backend" patch, you don't need to download anything, Infinity Ward said in a blog post. The update addresses two main areas: the new loadout slots being erased and stats being reset.

People who created classes in the newly added slots (you now have access to five more) will notice that they have been reset to default. While less than ideal, Infinity Ward said this will only happen once. Those who never created additional classes in the slots won't see any changes. The new patch also addresses a bug that could cause the game to kick players back to the multiplayer screen when they clicked on the slots.

The second item addressed in the new Modern Warfare patch relates to the error prompt that some players have experienced. Players who saw the error prompt and clicked "Yes" had their multiplayer statistics wiped, but Infinity Ward says not to worry. All progression-related statistics--including weapon progression, rank, XP, and more--are still intact and will be restored later.

Infinity Ward says you can still play Modern Warfare with the confidence of knowing your stats are being tracked. However, in some cases, the studio might have to roll them back once a fix is ready.

"We're actively working on a fix for this, but do not have one to deploy tonight," Infinity Ward said late in the night on January 22. "You are still able to play the game as usual and your progression will still track, but please be aware that once we do have a fix, we may have to roll back your stats to the state they were in prior to today's update."
