[BF6] The task "Treatment plant exploration challenge 2" is not completed.

I also tried it twice, but the challenge still didn't complete.
In both attempts, I didn't receive the 'Mobilizer Accolade' at all.
I believe the trigger for completing this challenge is most likely tied to earning this 'Mobilizer Accolade', and I suspect the reason it isn't unlocking is because the accolade itself is bugged and not being awarded.
