Unbreak my Heart clearly has the wrong level given to it. Besides using a level 25 item (Natron), it awards 27786 experience. BEFORE turning in a HQ version of the item! This is clearly supposed to be a 20 or 25 Levequest, but for some reason it's mentioned as level 10. Searching these forums, I found another player had mentioned this in the Quests forum back in December, so this hasn't been fixed since then..
