The issue with Mastery achievements not unlocking because you reached level 20 on the side mission and not the main is infuriating. I’ve been dealing with this for well over half a year and Im upset that they said they fixed it in the August update and that wasn’t the case. Any one else with this issue please post your console and which mission so they can see just how many people are dealing with this. I have tweeted them multiples times but never get a reply.
“One Night In Bangkok” - Reach mastery level 20 in Bangkok
Edit on 10th October. Got a reply on Twitter they are still saying it was fixed in the August update. Please more people tweet them so they know it didn’t fix.
