Hello @septicsanssam ! Welcome to the forums!
Sorry to hear you're experiencing difficulties with the quest "Breaking the Order". The way you're describing it, it doesn't appear to be a bug, your inventory shows the correct amount of Order Medallions (14) before revealing the Father (his is the 15th medallion). In order to reveal him, you'll need to fully complete the story, including the Hordafylke and Hamtunscire quests. The easiest way to confirm if you've done so, is to provide an image or a short video from the alliance map (Hordafylke will be added at the bottom once done).
