extremely minor bug, so not really high priority... by the same token it might be an extremely easy fix though:

when you use summon flame and ice elements for the first time, the mouseover in the status bar shows [8/8] for each.

then you buff up, use some of them in combat, etc. however, you do not use all of them in the 15 min that it lasts, and when the buff fades, you still have buffs up like glaring quills or ice barrier... so you re-summon the elements.

the mouseover then says the same number of elements you had when it last faded, on the new set. not [8/8] but something like [2/8]. once you use one of the new elements, the counter then adjusts to the correct number.

it seems to be "remembering" the amount that was left on the last set of elements, and I don't think that is really necessary.
