I am sure this has confused us all at least once or twice. You are doing a quest, collecting items, and then you run out of time, or space or something. So you need to abandon the quest, get it again, and then you should still have the items that you got so far right? Wrong...

With limited bank storage, many players were finding themselves with extra items that they didn't know what to do with. Usually these items were things collected from quests that had been abandoned and long since forgotten about. To help with both the storage issue of having too many items saved away and to help with clearing the clutter many players were being left with, items that are collected as a part of a quest are usually deleted when the quest is dropped.
