Skyrim had a couple of ugly ones.
First I had this one guy from a guild in Whiterun chasing me all across the world to lock me in dialog repeatedly. Turned out to be related to a bounty in another region, hah.
After taking a long break from the game I decided to go back and finish it and some sidequests. I endured the mind-numbingly boring civil war questline, taking all these keeps, only to have the final "bosses" of the questline be NPC-tagged and invulnerable.
