MORDEKAISER "W" Visual Bug

When activating Mordekaiser's W (Harvester of Sorrow) both the range indicator & AOE effect is nonexistent. The animation disappears for both himself and his ally. Upon recasting, all those metal shards to Morde like they should. This makes it difficult to judge the range of the W, and what it is hitting.

Upon the first few casts, the ability funcitons properly. But once it decides to break, it goes for the rest of the game. This has happened in every Morde game I played this week. Ill update this post with a screenshot once I grab one.
