Got gifted this game for Christmas and the same thing happened to me. Got boosted and tons of gold without knowing what was going on. I just wanted to play the campaign and enjoy leveling up a character. Deleted the character and remade them, no big deal on that end since they were brand new. But then all the account wide stuff sticking is really lame. Now the quest to get boosted keeps popping up in my log again and overwriting the main quest.
