Hello. So i got this error many times. Was wondering what can be wrong. Tried to search forum but no resulats. Maybe bad asks. So what was wrong with mine? I got auto quest accepter and completer. That was doing mine bug. Addons was faster then HB so HB thought it doesnt have that quest. This is for someone who will search same problem with exact message from HB window.
it happens to me when i turn in a quest before honorbuddy has a chance to do it. honorbuddy knows there is a quest to turn in, but cannot find it, because it has already been turned in exit out of hb, and restart. that way hb can compile the quests for that zone and know whats left to pick up and turn in.
