Repair Issues in scores and challenge progress

Every time I attempt to repair vehicles it will only award 20 score and never increase, even if I'm repairing the vehicle through various types of enemy fire. I doubt this is intended as I was getting hundreds of points before, but I think perhaps a recent hotfix or something else has accidentally bugged this progression. Not only in score for the round, it also fails to track properly for challenges it seems. Until it is fixed, engineers will not be properly awarded for one of their greatest team contributions, which may deter some players from touching the role until it is fixed.
