I'm actually experiencing this problem also (it's why I registered for the forums). It happened to me last night, and it keeps happening for me now after all the traditional user-end fixes (cache-clearing, hard reloading, etc.). It first started to happen after I updated completing "As A First Resort", putting me at 10 undone quests/subquests. While I do have 253 quest points, like I just said, I've still got a handful of quests left to complete. However, I did a bit of poking around-- if I give myself 254 quest points (by ticking the "Back to my Roots" quest), the quest calculator works properly again-- but once I untick the box and get 253 QP and 10 undone quests/subquests, it's back to saying I've done them all. Obviously a short-term fix on my end is doing another quest. But on your end, it looks like the problem might be something hardcoded in to a number-- either of quests, or of quest points-- and forgotten in a later update. For more details, in case this is helpful for recreating the problem, my undone quests (much shorter list than the complete ones) are Back to my Roots; Contact!; Dealing with Scabaras; Dream Mentor; Fairy Tale Part II - Cure a Queen; Great Brain Robbery; Recipe For Disaster - Subquest 9 Final Fight; Rocking Out; Summer's End; TokTz-Ket-Dill. Sorry if I wasn't supposed to reply here, especially on an old-ish topic-- I just saw it was the same problem I was having, and thought it would be better to post here than create more clutter with a superfluous topic. Hope my info helps, and if there's anything else in the way of details that I could provide that would assist you in locating the bug, let me know.
