Taking enemy Battlecast Alpha Skarner's crystal doesn't do anything visually

It's a confusing skin in terms of crystals, looking at 1 for the first time I had no idea if it was ours or theirs because there is no circle around it. And taking one just makes the big red circle disappear. That's it. Make it work like the original and do the small blue circle and the big blue circle, too, please. Thank you.
