I was playing a game versus a 
as a 
. I noticed that when I killed him, each time he came into lane, he had double buffs. First I thought that the jungler had given him it, but it happened every time. A friend of mine noticed it too so it can't be a client bug. How can this be?
LAWL that's a visual bug he doesn't actually have the buffs
It happens to Karthus and Sion as well. Notice that all three of these champions have a passive that "suspends their death" temporarily after being killed.
But when I mentioned the issue to a Rioter recently, they said they were already aware. So it should be fixed soon. (TM)
It seems that whenever you kill someone post-mortem with anyone with such a passive (sion, karth, zyra, or kog), the game -thinks- you'll normally take the buffs as if you normally kill them. You get the visual but you don't get the buff effects on respawn.
