[Gameplay] Vayne's E stunning on Trundle pilar when visuale is gone

During a ranked match, trundle got stunned by a Vayne E. This is nothing new. What did surprise me though his how he got stunned. As you can see in the movie he was stunned against his own pillar that was already visually gone.

1. summon pillar
2. Wait for it to sink down, then use Vayne E.
3. Stun on a visually removed pillar

I have not been able to test this from happening again because the timing is so hard to get. i still think this had to be reported for it didnt seem this is working as intended.
