Most of the items when you organize them go from the strongest of a type to the weakest of a type. I just noticed though that the elixirs do this (for the most part) except 1 has gotten switched around. The strong elixir 2 moves behind the strong elixir 1 when sorting so it goes...

800 health, 1600health, 400health, 200 health, 100 health (listing the order they are in in my bank). Which can be a little deceiving in battle because everything else is ordered correctly, so you go to click the lesser of the purple pots and end up burning the 1600 instead.
