[GAMEPLAY] Anivia - [Q]Flash Frost Goes On Cooldown Without Casting Spell

This is not the cast range problem where Anivia walks to be in range of the spell to cast it.

On Anivia, when casting [Q] Flash Frost, the cool-downs will start and Anivia will even turn to "cast" the spell but the spell is not actually cast.

This has happened 0-2 times per game (I play Anivia a LOT so I definitely notice when it fails to cast as I end up dying =] )

I have no clue how to replicate it but I do record my games via LOLRecorder so I can search for a couple more examples (and send the recording file if that helps?)

Here is a video of it: Video https://www.youtube.com/watch?v=Xl9aMH7wvfU

In the video you can see Anivia turn around for a second to cast the spell, and you can see the 0 cd on Flash Frost as well as the timer to set off the explode start. The direction is southeast. It's not the bug where the spell goes invisible until it explodes (super rarely happens and haven't seen in last week), this is seen by the fact that the minions in the direction of the spell (right by anivia) are not damaged at all as the spell would be passing through them.

Here's a url to the games match history and the spell is cast at 22:28 : http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1627696288 (i'm not sure if Riot records the gameplay data on your side so no clue if this helps but figured I'd include it)

Hope I provided enough information for you guys to look into this.
