Gameplay Bug: Twisted Treeline Shaco Doublekill on Galio

Map: Twisted Treeline Champs: Blue Side-Shaco, Zed, Annie Red Side-Galio(me), Ekko, Pantheon

I don't believe blue side had skins, Zed may have had his Shockblade Skin, but on red side I had Gatekeeper Galio equipped and Ekko had Sandstorm Ekko.

So anywho, during the match, I flashed in and ulted as Galio, on Shaco and his clone, Shaco managed to kill me after I had ulted, and he got a double kill and 600 gold (he said so in the match). Not sure if my death was counted twice, or because his clone had died as well during my ult, and the system considered his clone dying and my death to be a double kill. On the Announcement thing, it said "Kill" with Galio and then "Double Kill" with Galio as well again. Hopefully this made sense.
