I had the same "problem" with the experience too... How can I finish this quest? I went to the lighthouse, defeated everyone there, but there's no way to destroy the big machine on the top floor.
And what are those things around the island charged in 100%? Do I need to destroy them somehow? Also, there is some cave to the north of the island, but a grunt doesn't let me pass (though he moved from the door).
