[GAMEPLAY] Unable to autoattack a shaco clone after shaco has died

Playing a teambuilder game as Master Yi, killed off their Shaco off to the side of a big teamfight, and as low health as i was killing the clone wouldve killed me, however i forgot the damage it does and went to get the gold on it anyways with just 1 auto, but upon targeting it for an auto the game would autopath me back to base. I shouldve died.
