Bugs
 
It may be possible to mitigate this issue by doing the oldest active quests first. That way, only completed quests will disappear.
This bug can also be used to effectively remove infinitely repeating quests such as The Dark Brotherhood Forever or "Talk to the Companions leaders for work" from your quest list. Do these quests early on and they'll eventually disappear as you do other quests.
