I've completed all Battlefield 4 campaign collectibles and three endings on the hardest difficulty, but the corresponding multiplayer weapons remain unlocked. Battlelog shows I haven't finished the campaign, while both the EA App and Steam display completed campaign status and corresponding achievements.
Hello,
You're running into a known and frustrating issue with Battlefield 4 where campaign unlocks (especially for multiplayer weapons like the P90, M249, etc.) don't carry over properly, even though you've finished all the requirements. Since you’ve:
Completed the campaign on Hard difficulty
Unlocked all collectibles
Seen all three endings
Earned the appropriate Steam and App achievements
