I was doing my last wizard daily quest, and when I wanted to finish the quest I got an error message that I'm "not on a quest". It seemed that could not give the items to the wizard so I clicked quit. Now it shows this: "You've completed 11/10 quests today!" and I got the last 50 points token and the quest items are not in my inventory ... Just wanted to let you know :)

Quests do that to me all the time. It's something about the "Give Items" button registering a single click as a double click, IIRC. Obviously you can't be on a quest if you've already given the items ;)

Happened to me too, once yesterday with wizard and once today with library :I
