[Gameplay]When Yorick's revived ally kills someone with a buff, the ally keeps it when they respawn.
I believe it has something to do with the "Embarrassing Deaths in the Jungle" update? Not sure...
If Yorick ultimates someone and they kill an enemy with a blue or red buff, the ally keeps the buff when they respawn.
Happened in a game where Thresh killed me when I had blue buff, he kept it afterwards.
