[GAMEPLAY] Kalista Ghost Never Dies and Sticks To Walls

Okay, so unfortunately I don't have a screenshot, as I'm a terrible adc and don't play her much at all. I don't know if this is a glitch or intentional, but for the past 3 or so days I've been playing Kalista, I've noticed that her W acts erratically went sent to dragon pit.

After dragon spawns, send a ghost up the river angled at dragon pit. The ghost will fly into the pit , and begin bouncing off of dragon, slowly making it's way around the pit. It never dies, and it never leaves the pit. It can only be killed by a champion attacking it. so, in a way, it's basically a permanent ward .

I've noticed this bug occur with enemy Kalistas as well, one jokingly said "he's spooked by drag" when it happened and we had a laugh over it.
