Yasuo Windwall Bug [GAMEPLAY]

While playing Yasuo, the enemy team had an Amumu, his bandage toss did not get blocked by my Windwall once-Instead he was pulled to the windwall and allowed to freely ult our grouped together team (Though this should have been prevented) there were no minions or any champions standing beyond my windwall, and thus, no way that his bandage toss should have registered. On a smaller note, this is not the only odd thing I've seen in my time of maining Yasuo when it comes to his Windwall specifically. Things like Vel Koz W sometimes still registering damage even though it normally would be cancelled out but I digress. I feel as though this paticular bug has the potential to be game changing since that free Amumu ult easily could have turned the game around in their favor from that point on all because Winwall didn't block his bandage toss properly. Hopefully something can be done! Thanks for listening!
