Fix Memory Error 13-71 in Call of Duty Modern Warfare and WarZone

Many players seem to be affected by what is called Memory Error 13-71 when playing Call of Duty Modern Warfare and WarZone on their Windows PC or Xbox. It is a strange error, one you may have never seen before, but we’ve managed to gain a deeper understanding of it after a short period of time.

What is a Memory error in WarZone?

Not long ago, several Call of Duty: WarZone players complained about seeing Memory Error 13-71 whenever they make moves to load the game or when they are being added to a Regiment. We understand this issue affects players on the Xbox and Windows 10 computers.

A while back, the folks at Activision claimed a recently released patch fixed the problem. However, many players are still being forced to deal with it nonetheless. So, as it stands, we cannot rely on the creators of the game; therefore, we will have to find ways to solve the issue ourselves.

Now, there are several reasons why Memory Error 13-71 might appear, and we are going to discuss them all in this article, so keep reading if you want to learn as much as possible.

Fix Memory Error 13-71 in Call of Duty Modern Warfare and WarZone

Players of Call of Duty: WarZone who are affected by the ‘Memory Error 13-71’ should try the following fixes:

1. Delete the Regiment tag right away
2. Remove yourself from any active regiments
3. Disable the crossplay when in offline mode (Only for Xbox One/Series)
4. Contact Activision support for further help

1] Delete the Regiment tag right away

Chances are that the issue has only appeared after you’ve joined a Regiment or manually added the Regiment tag to your profile. If this is the case, then your best is to remove it. Yes, you may not want to, but right now, your options are limited.

In order to remove the Regiment, please open Warzone, and from the main menu, click on Barracks. From there, select Identity, and once your custom clan tag appears, click on it to remove the Regiment.

Save the changes made to the game, and that should do it for getting rid of Memory Error 13-71.

2] Remove yourself from any active regiments

For those experiencing this problem while trying to play a custom Call of Duty: Warzone match, then there is a chance it is related to the Regiment bug. Furthermore, if you are playing split-screen, then the other person must also be rid of it.

Additionally, try and make sure there are no active regiment invitations linked to both accounts. So, let us look at how to get this done.

First, you must open the game as you normally would do. Once you’ve arrived at the main menu, please click on the Social tab by pressing the F1 button if you’re on a Windows 10/11 computer. If you’re on console, select your account name to locate the Social tab.

After doing all of that, navigate to the Regiment category, then go to Regiment Invitations. Delete all invites located there.

Now, you should also see a Leave Regiment button in the same area. Please click on it and be sure to confirm your selection when asked to remove yourself from the Regiment fully.

Perform the same actions with the second account, then check to see if Memory Error 13-71 is still a thing.

3] Disable the crossplay when in offline mode (Only for Xbox One/Series)

OK, so from what we have gathered, the Memory Error 13-71 problem sometimes appears due to crossplay being enabled while in offline mode. We can solve this particular problem quite easily on the Xbox One/Series line of consoles.

First, press the Xbox button on the controller to fire up the Guide. From there, go to Settings > System > Settings > Network. Finally, choose Network Settings, then select Go Offline. You can now fire up the game to test if the error persists.

If things are still the same, then we suggest removing the crossplay option from your game. Go to Options > Account Crossplay. Change it from Enable to Disable, and that should do the trick.

4] Contact Activision support for further help

If all else fails, then your only option at this time is to contact Activision for further support. You see, there are times the company might shadowban users without acknowledging they’ve done this. It is not good practice, but that’s just the way things are sometimes.
