Prologue: The Final Test: "Master Assassin" Feat not unlocked when all "Assassinations" are complete

[Pikoki]

I've been doing the Challenges for the Prologue, and it seems that I can't complete the "Master Assassin" Feat, even though I have completed all the "Assassination" Challenges.

My "Assassination" Challenges page says "THERE ARE NO UNCOMPLETED CHALLENGES IN THE ASSASSINATION CATEGORY", but the "Master Assassin" Feat has not been unlocked.

Any ideas on what I could do?

8/8 10/10 7/7 4/4

Missing any?

I have everything on it unlocked so I'm not sure what you missed or if ti's glitched

So I'm 8/8 on the Assassination category, and I was expecting that to cause the Feat to also get unlocked too?

I just completed all the "Classics" and after completing all the suit only silent assassinations, the "Master Assassin" Feat also popped.
