Hey, not a major game breaking bug, but this can make Echoes of the Charge a little jarring to use.
When you cast Shield Rush with the Echoes of the Charge passive, there is a “cracked ground” effect under you that persists for a short duration. This remains stationary. But, when the 2nd AoE effect goes off, the cracked ground effect follows your character’s movement around until it disappears.
I believe this is a bug because the first “cracked ground” effect remains in place, and the 2nd explosion follows you. It’s a little disorienting to see “cracked ground” moving with your character.
