[GAMEPLAY] Katarina's Q vs Braum's shield

When I trow a dagger at Braum and he puts his shield up, he blocks it of course, but the dagger seems like it falls down in front of him but it just disappear, it wouldn't be that much of a problem if the indicator of dagger would disappear as well, there's an empty indicator of dagger that i can't interact with and can confuse me a lot and eventually cause a death. But i think that some patch ago i could trow a dagger at him and the dagger would still be in front of him for me to pick that's why it confused me really a lot and i thought I just can't pick it for some reason but then i found out that the dagger itself disappear. Don't know if the dagger is supposed to disappear and the indicator is a bug or it's just supposed to be blocked and the dagger should fall in front of him.
