[GAMEPLAY] Lux Invisible E

Recently played an ARAM against a Lux who, halfway through the game, her E disappeared. The little red dash lines in a circle would show up, as well as that mirage effect on the ground, but the sparkling star orb-thing was non-existent. Also, there was one point where a Master Yi on her own team became invisible by dashing through the AoE of her E.

Chatting with my teammates, only 3/5 of us saw this bug.
