Ahri spell bug

So I just tried a full wild comp and I must say. The way Ahri targets with her spell has no sense... I think the way she targets is the lowest hp champion or "optimal" target but 10/10 times the main focus is a target out of range and does nothing. I've seen her try to use the orb spell on a Draven 3 TIMES and it didn't hit once, cause they were too far one from another.
