Fiora Riposte Bug

Fiora's riposte does not stun on certain CC's anymore. Specifically, cc that is cast by empowering an auto attack (examples include, naut auto, blitz E, renekton W, TF gold card, etc). This bug has a 100% reproduction rate and can be very game changing in certain situations. I have had this bug happen in my games many times and it changes the gameplay drastically when faced up against these champions. Fiora's parry states that "If Fiora parries at least one immobilizing effect, Riposte Stun icon stuns the target for the same duration instead" and since these auto attack enhancers are all immobilizing effects the should trigger the stun. Everything else about the skill works properly, the damage is blocked but it just does not trigger the second part. This bug is only big because it is noticeable and has a large effect on Fiora's gameplay.

Hopefully this bug gets fixed soon thanks for reading :)
