Summarize your bug On certain vehicles, Kills/Assists/Vehicles Destroyed does not accurately count into equipment unlocks. For my M1A5 tank, I have kills accurately register to unlock the smoke launcher and repair system, after that the rest of the pending unlocks still show 0 progress. Same issue with my AH-64GX helicopter, it shows 14/40 towards my 127mm rockets but 0/120 for the 70mm rockets. Restarting the game and trying again does not seem to help.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Not sure. It's inconsistent across different vehicles. Eg. my T28 Tank register kills correctly but the M1A5 does not
What happens when the bug occurs? Kills/Assists/Vehicles Destroyed during the match will not count towards certain unlockables which is very frustrating.
What should be happening instead? Every unlock should be tracked correctly, there should be no inconsistency between equipment for the same vehicle.
