[GAMEPLAY], JAYCE

I just played a game of in ARAM and something is very wrong with Jayce. In Cannon Stance when my "Shock Blast" (Q) goes through "Acceleration Gate" (E) and i missed (therefore the skill reaching the end of the path), my projectile doesn't explode and deal AOE dmg, but disappears completely (including visuals).

Just to help, these are the official description of jayce's skills Q: Fires an orb of electricity that detonates upon hitting an enemy (or reaching the end of its path) dealing physical damage to all enemies hit. E: Deploys an Acceleration Gate increasing the Movement Speed of all allied champions who pass through it. If Shock Blast is fired through the gate the missile speed, range, and damage will increase.
