There are so many skill challenges, hearts, dynamic events, and NPCs that get bugged and are not completable (seems worst in the Ascalon zones, for some reason). When there were resets and patches every day, many of these got “unstuck”. Now that there aren’t regular resets, these bugged events/etc simply stay that way for hours or even days.
Until you get things running smoothly, a regular quick reset would help a lot of people trying to complete maps.
