I spent my other 72 leves last night just chain starting-quitting Where the White Morbol <something>. It's a level 58 leve in the Hinterlands, and it seems to only have two chest spawn locations, both of which are visible from one spot. I would pop the leve, look for the chest with one swing of the camera, and then abandon/get chest and retry. It took maybe 20 minutes to tear through them all.
