Platform, device version and operating system
Xbox (Series X)
What you were expecting to happen, and what actually happened
The Hard Taskmaster achievement is not unlocking on the Xbox platform. There are not enough tasks in the campaign to meet the achievement requirements. Completing all tasks did not unlock the achievement.
I can confirm that the same problem is also present in the PS4 version. Per the various PSN trophy websites, no one has unlocked this trophy since the end of the previous campaign.
Hello 
Thank you for reporting to us know about this issue.
I’ve let the development team know about this bug!
Hey, I’m new to the forums, but I was wondering if the devs are going to look at fixing the Hard TaskMaster achievement because this week is the conclusion of the campaign. I can confirm this achievement is still an issue.
Also confirming it’s not unlocking. Have completed all tasks for the current campaign and the achievement is still locked on the Xbox platform.
