Jade Fang Cassiopeia miasma bug?

Type of Bug: Gameplay Summary of the Bug: Jade Fang Cassiopeia (so far as I'm seeing) sometimes will have the Miasma projectile become invisible when it lands, not while it's in the air. Reproduction Steps: Play Jade Fang Cassiopeia and use Miasma multiple times. Check to see if the player finds the Miasma to be invisible when it's on the ground, then if the opponents or allies can see it. Reproduction Rate: When I saw the bug, it happened more than 3 times in the game as I remembered. Forgot how long the game took. Server: NA
