Gameplay Bug - Sated Devourer Aatrox

Sated Devourer's Phantom Hit seems to sometimes disable Aatrox's W (both toggle versions). Sometimes it will work every other hit as it should (like Vayne's Silver Bullets). Other times it doesn't proc the W hit at all. To reproduce the bug, simply achieve Sated Devourer in-game with Aatrox.
