Most likely it is a problem with quest phasing (where u have to kill lots of mobs from cannon tower). If you had this quest undone - retake and drop or end it.

well i did that part of quests, and i got quest to fly to north icecrown to talk with some soldier and i should then go back to complite quest but then it happen puff and quest chain is restarted and i need to kill again lots of mobs .....

p.s. i did that long time ago, and this happened only today, i am flying over that part of map several times a day
