Anivia ult clarity

Not sure if this has been fixed and it's only a spectator bug (since I was spectating the game I saw this in) but I've noticed anivia's ult doesn't sit flush on the entire surface when the terrain is uneven (on slopes for example).

If you're standing on the top side of a slope, you can't see yourself standing in anivia's ult if the middle of her ult is in the middle of the slope.

Think this is a clarity issue that should be fixed.
