Assignment unlock from BF4 campaign not unlocking.

Same problem here. I completed the campaign. And I replayed the last level three times to unlock all three weapons. But I got only the reward of the first attempt.

So I unlocked the QBZ-95-1 but I miss the P90 and M249.

I also recognized that It is not possible to see the whole credits at the end. My screen freezes there on some point.

Please fix that!
