This issue actually points to a more base issue with the quest tracking system. Namely that we can't choose which we will or won't track freely. That is the part that is really broken.

As for the accidental abandoning thing, it sucks, but I don't think you'll see a ton of sympathy since in the end you clicked through the abandon dialog without looking first, not really anyone's fault but yours that you lost your progress.

If you want to take a serious stab at helping this never happen to anyone else, or yourself in the future, then go after the actual problem. The fact that we can't choose to track or not track quests freely.
