Sceptre with Discipline Aura - bugged Spirit costs.

I found a Sceptre with the Discipline Aura with +3 Minion Skills and +30% Spirit, so an obvious upgrade.

The problem I have is that if I try to equip the Support Gems (Vitality, Clarity, Herbalism) it increases the Spirit Cost exponentially in addition to the cost of the Support Gems by themselves.

For example, if the costs are:

Vitality + 20 Spirit
Clarity + 10 Spirit
Herbalism + 15 Spirit

I would expect that if I have >=45 Spirit available to reserve, however in my test even with 78 available Spirit, equipping these supports disabled the Aura from the Sceptre.

Isolating just one Gem for this example I used Herbalism, and put Vitality and Clarity back into Grim Feast.

Now I'm showing as having 21 Spirit available. So I would expect that I can add Herbalism into my Discipline Mace sockets, and reserve 15 Spirit, but instead it disables the Discipline Aura.

+1 to this (it applies to all auras that are free of cost) please fix it or either make it clear that it doubles the amount of additional spirit reservation on "free" auras like Sceptres or other free skills like the blood mage ascendancy skill "Life Remnant"

haveing the same issue.
