Mongoose Destroyer Achievement Not Counting

Hello. I’ve noticed for a while now when I destroy an enemy controlled Mongoose, on screen I am notified of a Destroyed Vehicle. However, the Mongoose Destroyer Achievement counter does not add new kills. I am stuck on 27/50. Has anyone else reported this, and is there a fix?

I know what is the problem, you have to destroy the Mongoose meanwhile it is OCUPIED by a member of the enemy team. Usually when you shot them with a cannon the players are expulsed violently of the mongoose, and it explodes without a pilot on it. It’s funny, because the Mongoose destroyer achievement is the most difficult of all Vehicles Achievements. Good Luck!!! Keep it going.
