A triple-restore potion can be made in more than one way, such as:
Columbine + Mountain Flower + Lady's Smock
Columbine + Dragonthorn + Bugloss
However, potions made in these 2 ways, though exactly identical in effects, do not stack!
I am told this is because of the order of Health, Stamina, Magicka in each, even though the tooltip on the potions shows the order as also identical.
I wish this behavior would be improved so that identical potions stacked regarding of any "order."
Thanks!
