2 riven glitches patch 5.6

Build attack speed Riven and her w struggles to resume auto attacks. She can manually reengage fast but the auto attack system for the skill lags like .5 sec. I also Successfully knocked up an enemy with her Q right as a Cait sniped my target. She got the kill, but I did not get an assist or apply damage even tho they got knocked up. Need to adjust the damage timing to be on knockup hit or just faster in general.
