Healing power bug

When I used the healing power with Odysseus, both in practice and in battle, 2/3 of the times nothing happens but it triggers the powers cool down.  This is new in the last few hours. 

Hello TheDon,

Does the visual effect of the power appear or nothing at all, except the cooldown being triggered?

No healing effect or visual effect, only the cool down.  

Update: this hasn’t happened again since the last server update.  Go figure.
