[BUG] Titan's Breath & Cast Time Spells

Anytime a Shrill Lord hits one of my champions after they've started a cast time, but before the spell has gone off, the UI goes haywire.  If the champion does not resist Titan's Breath they are knocked down.  When their init comes up they are unable to cast (the UI is gray no matter where you place the spell, in my case Blizzard) and you can't skip them.  Only option is to hit auto resolve.  Even if you cast blizzard at a spot where there are no friendly troops you get a "Can't Use Ability" box with no text inside the box.  Just the okay prompt.
