Especially the Chest Icons for the Lost Caches and the One-Shot Caches are very uninspired.
On top of that I think all the different caches should have:
a) different minimap icons
b) should visually look different when looking at them. So they are all distinct.
Especially when finding a Runesmith Cache I would love to visually see it and not needing to hover over it with the mouse, to see what kind of cache it is.
