Anivias Flash Frost Glich

occasionally, when casting Anivia's q, the range indicator for the second part of the q (the blast/stun circle) moves around (not accurate to where it would actually go if the spell where to be cast), mostly around terrain like trees. This kind of makes it pointless to be there in the first place. Sometimes it only shows the skill shot (which is better then having this glitch occur). more importantly, sometimes when casting Flash Frost (through terrain or otherwise), the projectile simply disappears, leaving the second cast up to instinct since the projectile cannot be seen.

fix this asap pls
