Engineer Specialist 3 and vehicle repairs not working

Okay so I just completed Engineer Specialist 3, in the next match after i commented the above. Both engineer specialist 3 and weekly challenge has been completed. Idk if the devs did something or what, but thank you 

The issue still persists even for this week's weekly challenge its not working. And for some reason the mine damage i did to tank counted towards air craft damage challenge.

The issue remains as of 12/17/2025. Been trying to complete the engineer specialist 3 challenge and cant seem to make progress with healing vehicles. 

still broken with winter offensive update

The issue is still there in PC... 12/12/25

Same 07/12/2025, PC

Same 12/07/2025, Xbox One S.

Also happening to me on PC.

Same... still not fixed. PS5. 

Same. No progress on repairs. Have tried green and blue repairs; anti armor and combat engineer career paths, tracking and not tracking challenge. No dice.
