In the past season (Season of the Deep), I had 6 seasonal challenges being tracked. Now that the season has changed to Season of the Witch, I cannot track the new challenges to be pulled up using my ghost during play. It tells me: "NOT ENOUGH ROOM - You can only track 6 items at a time. You need to untrack other items before tracking this one." However, I cannot untrack the other items because they no longer exist, yet they are still being tracked? Is there a way to fix this?
