Repro:
1. Pick Earth Spirit and learn Rolling Boulder
2. Create an enemy Invoker and Silencer or Pugna, level up Cold Snap and Last Word or Nether Ward
3. Cast Last Cold Snap and Last Word or Nether Ward on Earth Spirit
4. Use Rolling Boulder


Result: Cold Snap's mini-stun correctly cancels Rolling Boulder to Last Word's or Nether Ward's damage, but the visual effects of Rolling Boulder are still created and remain stuck permanently.

Expected: Visuals effects cancel together with the ability.
