Adonia's Ego Pinnacle of Power Skill Disappears from Hotbar on Zone Change

When changing zones, the Pinnacle of Power skill from Adonia's ego disappears from my hotbar no matter what slot I assign it to.

This occurs when I enter a map, a campaign zone, a town, my own hideout, and even abyssal depths from within a map.

This same error also occurs with Whispering Ice's Ice Storm skill.

Hi, there is a quick workaround for this. If you place the power siphon skill that comes with Adonia's Ego on any other key, it keeps Pinnacle of power from disappearing on zone transfer. (Though we shouldn't have to do this)
