Ability Buffering Bug Riven (maybe more champions)

yo i have experienced really weird buffering issues with Riven!

I press E -> R -> Q -> W which SHOULD translate into: E-shielddashing in, activating my R (that animation gets cancelled cuz of doublecast with E), Q-dashing forward and W-stunning my opponent.

I usually "smash" my buttons to get the fastest possible result (so i basically press the buttons before the previous animation went through) and ever since 9.4 was implemented I now get "stuck" in the animation.

So 1 out of 10 times when I use E R Q W the result is: E-shielddashing in, activating my R, Q-dashing forward, Q-dashing forward a 2nd time and W-stunning.....

I cannot interfere with that process of animations at all. I cannot AA in between, i cannot stop the animation, I cannot flash. I am basically stuck in that sequence of animations.... which is really fkin annoying!

Please fix that. I dont know if it has anything to do with the VFX update, but I am 100% certain this bug did not exist previous to 9.4!
