Anivia Q bug

Today i have started to play Anivia and the first game I played went fine at first but then i noticed something that didn't seem quite right. Flash frost, the Q on Anivia seems to be bugged, you can fire it in a straight line and then detonate it by pressing Q again. When it detonates it with freeze anything caught in the blast radius. It seems that when ever i went to use it did not go off correctly or was on a sort of animation delay. Meaning that the actual effect was behind the animation and or it just didn't hit. I wouldn't normally report something like this if it was not have effect on a kit, but seeing as Anivia's kit is based off of her Q,E,R combo its a big difference. In lane against an enemy i throw out my Q to stun the enemy champion, they are inside of the animation and i reactivate it to get the stun. It does not proc and they walk free without being stunned or even slowed. I am going to play more games to be sure that this is happening more often and will report back, Anyone else that seems to notice this on anivia i would very much like if you commented. Be back in a
