Cold Snap + Spell Cascade Has No Spread

Hi, great league! :)

Cold Snap, when linked with Spell Cascade doesn't affect areas in front and behind of the cast anymore. It appears to be damaging thrice, but like Spell Echo in one area. I didn't see any change in the Patch Notes so perhaps this is a bug?

When using Cold Grasp or Overseer skill effects, there are three casts displayed, but no damage in the other areas; when the animation clears only one chilling area remains. It does not appear to be a visual bug?

Forgive me if I missed a change somewhere :)
