Ha ha.....one of those "KB got me again moments"!

One small piece of advice for down there.
********Spoiler Alert*********
There's an NPC on an island that wants you to find his lost gold. After you accept the quest, explore ALL of the waterways. In certain places, a dialog box will pop up and ask you if you want to search here. Say no, quicksave and then float back over the place and search. If you find the gold he's looking for, reload, remember the spot and keep searching. iirc there are 4-5 locations, of which at least 1 has a magic rune! Once you have searched all of the water, go back to the spot where the gold was and grab it then. The other items will disappear if you get the gold first! Also, when you go back to the guy, if your army is good, you can fight him for some good EXP and the quest still completes.
