@madeezy I have the same problem... I hope this will be patched soon, very soon, because I don't want to play 100h+ again..

Having same issue, glad im not the only one

@ricekid007 me too have the same problem, I have no idea how to fix it, it is the last part of the game and cannot able to see it and the worst part is I am playing it using uplay+ and my subscription is going to end in 2 days.

After u finish the game and in post-game u cant complete the last order of ancients dude, because father is bugged out, from 5 of 6 clues. There are already many threads from this problem if u see this ubisoft please put this problem in the megatread this is a game breaking bug.
Hytham wont talk to u so u cant finish that quest, i really hope he does speak to u after the patch from today if not i am not going to play any further i wanne see the outcome of the last order member alfred, and the weird thing is i already have thors hammer and set.

They need to fix this bug i hope they can reproduce it so ubisoft sees it for themselfs.

@ricekid007 I have the same bug, I have finished the story, collected everything in England and killed all of the 44 order members and I have just 5/6 clues for "The Father". Because of that I can't do the last mission from Hytham. I have played 110h. And I did not received the achievement from completing Hamtunscire Arc. Maybe from there is the problem, from Hamtunscire. I hope this will be resolved very soon. 

@alexandru27p Same situation. Except I've completed everything. Ubisoft told me it was a bug in a ticket I made. I uploaded videos and tons of screen shots.

@d4rky26 Was not fixed today. very upset about it.

@madeezy u are right i give up on the game for now for this ancient of the order game breaking bug. And i still cannot talk to reda @ ubisoft why is this game so broken on many quests ?

@hostlean same problem this is game breaking i even have 8 medallions left in my inventory.

@guest-q6wy1ycf same problem here

I spent hours finding every zealot and order members, but I only have 14 out 15 medallions to give to hytham. He does appear near the longhouse. Is there any way to fix this bug, or it’s just broken till next update.

same problem here. @ghxstfacke

All lets post here to make this important it has to be fixed.

I have completed all the story and areas and the father is still not identified. Is this a bug that makes my game unfinishable?

@eaglesfn I have the same issue.

After completing Hampshire arc I got told to talk to hytham and he gave me Thor's helm. (Which was ment to be the given after the father is killed I believe)

Now I have the father unidentified no achievement and no mission.

I've killed everyone else in the order and have done everything else in the game.

@ghxstfacke
1.0.4 still have same problem

I played the mission long before I even start killing the order of ancients... now I'm at a halt.

@d4rky26 kinda same I've done every Pledge quest and the main story as well as killed every other order member but the father stays locked. Theres no more quests left to do. I dont want to restart after logging 116hrs in the game.

@thor_royalton same here buddy over 120 hours here this is not acceptable.
