[GAMEPLAY] Fiora W not triggering (stun) when parrying Twisted Fate W Gold card

So this happened in my RANKED game, I think every time I tried to parry his W it just came off as a parry and not like a stun. I know for a fact that this was not the case earlier.

Luckily I won the game but this could have been gamebreaking and it kinda was in some situations.

I only included two examples in the clip but I think that's enough, one is very clear.
