Node "Spectral Ward" bugged

The Node is bugged if it provides the only source of ES you have. You lose your energy shield as soon as you click a mana flask. (Maybe life flask aswell didnt test it and hard to see since you regen your life at the same time)

On my Character my ES (71 energy shield) which was only provided by the node, i lost all the energy shield if a pressed the manaflask. Of course there were no specific mods on any flask/tree or gear which would have made me lose ES by clicking flask.

If i equipped a piece of ES gear (in my example helmet) on top of the node, i didnt lose my ES anymore as soon as i clicked mana flask.

I was surprised and saw a reddit thread from one user who had the same issue.

The User thought that its the chest piece but based on the gear (staff so prolly also in the same area of the skill tree and maybe clicked the node aswell), i think that it could be the same problem since it was described as only losing around 250 ES which corrolates with the chest pieces which has way more Evasion then mine.
