Ryze E bug still in?

Hello, I just finished a game on summoners rift, was playing support morgana and the enemy team picked Ryze. At one point here comes a team fight, I make the mistake of being out of position, Ryze comes really close to me, 1 v 1, uses the Q, the W (all normal here) and then the E and I insta died. In the Death Recap screen it was stated that his Q and W did 300 and 250 damage while his E did 1000+ damage. The time it took to kill me was 0.46 seconds. He didn't really have a great score but he was farmed (had fully stacked archangel and Roa + a glacial shroud) and ofc he's Ryze, if you are too close to him he's gonna hurt you, but knowing that there used to be a bug on his E that instakilled someone that was too close (The only way I can describe it is that the projectile starts bounding between the target and Ryze and it might register too many times in a row so...BOOM) so I don't really know. Is it intended or the E is still bugged? If i'm not mistaken the problem was never solved so it might be just that. Hope this helps in some way! And bye!
