[Gameplay] Kallista W Bug

Reporting a bug where Kalista can aim her W on dragon from bottom turret and the autopathing will lock her wisps in, Allowing her to stack them up as much as she wants until dragon is either slain by friendly and they disperse or they act as glitched sight stones for ganks. I'm not sure if this is intended or already known, But it was a very very frustrating match for our team. We almost instantly surrendered when the time hit 20:00
