Same bug, but with slightly different variables.

• Finished the main story
• Completed all regions, including the Hamtunscire arc
• Killed all Order members, except for The Father
• The Father is not revealed and has 5 out of 6 clues
• Hytham is in his cabin and has no other dialogue
• I have 14 medallions in my inventory, Hytham needs 15
• I have not gotten the Thor cape
• "Breaking The Order" quest is still active

The Vinland fix works, but it will reduce your quiver level. So if you had it (almost) fully upgraded, you just lost a lot of stone, leather and fabric. A fix for a bug that reveals a new bug.
