Warzone developers have finally responded to an issue that is causing certain weapons to not gain XP in Season 3. 

While the Warzone Season 3 update introduced new guns, balance changes, and modes – a number of players have reported problems with leveling up certain Vanguard weapons. 

This issue is obviously incredibly frustrating, particularly when the best Warzone loadouts require high-level attachments. So far, a total of four guns have been impacted by this bug, with the KG M40 and NZ-41 being among them.

However, the developers have now finally responded to this problem, reassuring players that the weapon XP issue is being looked into. 


Raven Software has now released a patch that has fixed the weapon XP issue. This means players can now fully level the KG M40, Volkssturmgewehr, AS44, NZ-41, and Gorenko Anti Tank Rifle without any issues.
