[GAMEPLAY] Heimerdinger Turret Bug ( Kinnda.. )

Hey.... I was playing heimerdinger today and i found a bug. When i place turrets and, i cant remember what champion specifically, but when some champion uses their ability that flings things into the air.... i found out that the turrets say in the air and don't come down until i place new turrets.. i don't know if people are able to attack it but its just little weird.
