Aatrox scuttle crab gameplay bug

When the scuttle bug is cc'd he is supposed to lose the majority of his Magic resist and Armor. However when the champion Aatrox knocks up the scuttle crab using his Q(Dark Flight) it doesn't remove the mr and armor from the scuttle crab. I was able to replicate this bug every time I attempted to. I even made sure it wasn't just my client reading wrong by showing a friend and him confirming. I know it's just a minor bug but it can really slow down an already weak jungler's clear time. Thanks for taking the time to read this! Sincerely, Quadapus
