Gragas q glitched?

I just played gragas in my previous game. on my 3 e into a gromp my e went all the way threw and did not do damage. It also happened at a baron fight and my teammates saw to my e went though a tryndamere and i went over the pit. I thought maybe i lagged or something but my team mates saw it to so not sure if its some glitch with the past update? anyone else have this problem.
