I have a problem when I am carrying nethergon energy and super mana potions. Super mana potions are showing on the button. However, during a fight, if I take a super mana potion, the icon will change to the nethergon energy, and clicking the button again when the cooldown is up will not try to use a super mana potion. I've also noticed the icon jumps around a bit since it can't do anything.
Is this just a limitation with the Blizzard API and in combat stuff? That was my assumption, but I thought I'd ask anyway. Thanks.
I'm having a very similar problem if I have both Mana Potion Injectors and Super Mana Pots in my bags and I click one during combat, the icon changes to that of the other and it will start using the other item when I click on it. Sometimes it even gets confused between 2 different stacks of Injectors and will use pots from each one instead of depleting one stack fully and then starting the next.
