Hmm, well seeing as I haven't done the Island Paradise quest and I am able to go across to the island where the target is, I would have to say something is up there. I was able to cross to it and do the magic, gun target and sword hitting until it's on a rock and has a sword target on it. I cannot reach the target as its slightly above me. I have tried to go above and find a spot to vault, to no avail. I am on the island with the ruins, anyone know how to get to it? *edit* I have done all the other quests in Driftwood, just not the Debt quest.
