Thresh hook didn't CC Malzahar w/o passive
(Thresh) I basic attacked the Malzahar to pop his passive which only lingers for 0.25s, then attempted to Q hook him (has a 0.5s delay as opposed to 0.25s Malz passive) and although he used W on top of himself, the voidling was full health and my hook just vanished. He had a Morgana on his team but I checked thoroughly through the replay, her black shield never went on CD (was never used) and Malz passive buff icon went on CD (look for it in video below!) before my hook even left my model, yet he was unaffected, took no damage or CC. I don't know how to make videos but I used the Replay feature to record it from both Malzahar & Morgana's perspective. If it's not a bug then the game should show that the Voidling taking damage and thresh hook SFX. I have 2 videos and recorded it at half speed.
