[GAMEPLAY] Ezreal's W splitting into two missiles

Noticed this during a bot game: Ezreal used his W and it split into a V-shape when hitting an allied Volibear that was being suppressed by a Skarner R. Ezreal had max stacks of his passive, Phage, Sheen, and Zeal, and the W triggered Sheen's passive. Skarner had Stalker's Blade-Runic Echoes, which did not pop with his ult, and Volibear had Bami's Cinder and his ult and passive were both activated. No clue if any of that is related to the bug but hopefully it helps. The split appeared to have one W missile going the same way Ezreal fired the original spell, and another missile off at a rough 30-45 degree angle. No idea if either missile could apply W's effects.
