[Gameplay] Darius Basic Attack not attacking other Champions.

During a ranked match that I just competed in where i was playing Dunkmaster Darius i found that if i was trying to auto attack a champion none of my attack commands would work. Example activate W then right click on Aatrox no action would occur W would be active but no basic attack would happen. Even if W was not active the same bug would occur and this occurred against all the champions that i was facing. This occurred on summoners rift. Attempted to replicate in a custom bug didn't occur.
