[Gameplay] Dunkmaster Darius random lockup

I found this to be incredibly frustrating to suffer through. Throughout the dominion match as Dunkmaster Darius, my character would randomly cease to listen to mouse input, carrying out his last order. Instructing darius to move or attack when one of these issues is occurring achieves nothing, as he continues to blunder into the tower, or stand still during a teamfight. I feel it is connected somehow to the fact that I press spacebar frequently to acquire my location in teamfights, snapping the camera to my position. I went through my keybindings, found no conflictions, and even unbound everything except right mouse click, still having it happen.

I have never experienced this before, and it continued to plague me whether i disconnected and rejoined the game, and even after i restarted league before the second game i played of Dunkmaster Darius Dominion. I really cant come up with reproduction steps, but during the second game i took a recording of the game in its entirety for examination.
