Project Ashe Ult Bug - Fired Opposite Direction of Cast

So I was trying to send an Ashe ult down the lane in preparation of a roam from mid, but the ult went behind me. As you can see in the clip, my range indicator is towards the enemy bot lane and my cursor isn't hovering the minimap. Yet, my ult went behind me. Not sure if this is exclusive to the Project Ashe skin, but this happened in the first game after I bought the skin. And I've never had this issue before.
