Kayn’s Tower Shot in R Bug (And Riot’s Response)

??????????? This bug has affected tons of Kayn players since his release and I know for a fact that this should not happen. You become UNTARGETABLE. Master yi q, Maokai w, Xayah R, Zed R, Fizz E, etc. are untargetable and they don’t take tower shots because the shots get cancelled. Why is it different for Kayn?
