soul storm loot chests disappear when you die, even if you havent opened them

if you complete a storm tower and then die, the loot chest will be deleted, even if you have not opened it or gotten you loot. this happens for the chests on towers 1 and 2, and for both chests on tower 3.

dying to the boss or a random mob after defeating the tower happens a lot and means you lose out on the loot you are supposed to get
