I have noticed that veigars stun can become invisible when placed partially through terrain at points. It does not show the stun, nor the channelling and effects of it being activated. After speaking to the enemy veigar it appears that he could see it no matter what, but I could not.
It's an exploit that most champions can use to their advantage.
This is not a bug however, and is intentional.
Sion can channel his stun in a bush and enemies can't see the indicator that it's charging, allowing for a sneaky stun.
Pantheon can launch his ult in a bush and the enemies would not know he's dropping in.
I admit the veigar stun technically should show in this case like Aurelion Sol comets thingy
makes me wonder if Thresh, Camille and other Zoning type abilities appear when launched or hidden in a bush?
