From a recent update:
"ITEM: ...Shining Droplets, Clean Fire, Clean Air, Clean Earth, Clean Water are now stackable up to 100."
I'm confused. As far as I know these items are not used for anything. They were removed from the solo aura quest shortly after the quest went in because of problems with alchemy combines not being no fail. Why are they now stackable? Wouldn't it make more sense to remove these items and make the other items for the solo aura quest stackable?
