[GAMEPLAY] insane darius bug, desperately needs fixing

Under certain parameters, Darius will apply two stacks of bleed with auto attacks, leading to insanely easy kills by just getting noxian might near instantly. When Darius reaches 440 movement speed at any point in the game while owning sated devourer and having damaged an enemy with tiamat, he enters a persistent bug state in which owning sated devourer and any other items(but not just sated devourer) cause his auto attacks to apply 2 bleed stacks on each hit(4 on phantom hits), regardless of hitting with phantom hit or even being at the movement speed threshold. Also seems to trigger when owning tiamat or ravenous hydra and sated devourer before hitting the movement speed threshold, but ceases to work when selling tiamat(or ravenous hydra). I tested this extensively in custom games and can produce these results 100% of the time.
