I am not sure what changed on the back end with the new Highsteppe patch.
It seems to have brought back the pally bug though.
If you have the Plea of Divinity orb active on your hand, you cannot use your super (at all) even though it has also spawned on your hand.
The only way to get rid of this is to give the rez-buff to a player. Which gets rid of the Plea orb, but also uses up your super immediately (wasting the heal).
This bug makes Plea of Divinity actually harmful during a fight as it is preventing a tank from healing using their super.
