DM7's mastery level is stuck at 9.

And the DM7's kill count is also stuck, so I can't unlock new attachments.

I've been experiencing this bug since the game's release and it hasn't been fixed with a recent update.

I'm playing the official game mode on the official multiplayer server without any unauthorized programs.

I have tried all the methods listed on the EA website. I checked the network status and completely deleted and reinstalled all files related to Origin and BF2042, but I couldn't solve this bug.

This bug was beyond my ability, so I contacted EA for help, but they said they couldn't solve this bug.

If you can't fix this bug now, please log this bug. I hope to get it fixed in a future update.
