I watched the Hannibal episode Coquillies when it aired last week then marked it as watched and today (4/30) it showed on my tracker again. When I mark it as watched it still stays each time I refresh the page.
Sorry for the confusion. We've shifted around the Hannibal listings a few times due to the pulling of Episode 4 (and then it's subsequent availability online).
It's possible this is what has messed up the following episode, Coquilles, on your Tracker (when moving/renumbering the episodes). Please go ahead and try marking it as watched ONE additional time and see if this solves this issue.
If not, please let us know here and we can look into things more.
