Challenges not counting progression.

I didn't notice any action (revives, kills, etc.) not being counted towards the progression, but I noticed the challenge progress display may be off often. There can be even a difference between the general challenges list and tracked challenges list, where the tracked challenge usually appeared to be up to date, but the very same challenge in the general list was behind. Even when the challenge was completed and properly disappeared from the tracked list, it was still hanging in the general list. It looks just like a client display issue with the progression still properly tracked in the backend to me.

Yeah same here! In game I got two of the challenges done (recon and assault classes) and then in the menu it shows the progress bar completed but no check mark. It’s almost like I passed the number it wanted and it’s still counting.

I am also experiencing the same issue but with the recon class for spotting enemy's, it just keeps going back down after a match, hope they can fix this soon 

Yes. I have completed 3000 engineer vehicle repair challenge twice now. And again it has reset back to 2,122/3000. My Support class was at 63 revives for my last match where I had 23 revives. So the total should have been 86. But instead I lost revives and it went all the way back to 27.

Beta isn't the reason either. DICE hasn't been able to get this right for many years. They've had this problem ever since they changed the model to non-persistent servers in BFV. Something breaks with the dynamic server instances. I think the game server has to update a central server database for your player. And it constantly breaks. Sometimes it will catch up later. But, often it does not and you simply lose progress. 

Its a bad architecture that doesn't scale well and never gets fixed properly.

Same here with the revive challenge. Was on 86/100.... finished another match with 20+ revives and went down to 70/100 :-(

Having the same issue with Support. I was at 80 of 100, played multiple matches, saw the completion reward ping in game, so I switched to engineer to work on that, played a few games, then when I exited, my support challenge said I was at 80. 

I had that with the Support class, too. I was at 76/100, and then it showed me 10/100. 
After that, I quit the game and restarted, and then it showed me the correct score. 

I also achieved 100 revivals as a support class, but was reset to 42/100.

Update, after relogging the game, the progress was updated to complete the challenge to 100/100.

Later on, I had the same issue with the 'repair' challenge for the Engineer. After reaching the 3000/3000 goal, I got the green checkmark. After a few more matches, it went back to 0/3000. Relogging fixed this to return it to 3000/3000.

This seems very buggy, but luckily the progress is not lost.

When I was playing, I managed to complete both the Recon and Assault challenges, and I got the notification that I finished it, went into the Main menu, checked my Challenges, and it got untracked, and I lost about 1/3 of the progress I had in total.
