If the actions that led to you achieving the quest in the first place were later canceled or nullified, the points awarded for the quest will be retracted as well.
For example, if you had a quest to resolve 10 tickets in a day and you did so, you'd be awarded the respective points for that quest. But, at a later point in time, if any one of those tickets is reopened, the quest would be canceled and the points removed.
