Anivia Q Disappears

So I guess I thought this would get fixed ages ago since it's kind of a champion breaking bug, but alas, it has not, and since I main Anivia, it really hampers my gameplay, so here's my report.

When Anivia Q's, sometimes the ball disappears along the trajectory. You can still proc it's second Q, but unless you have an innate idea of its speed and direction, you'll probably miss (though it does give hit enemies that ice debuff so that helps too). I can usually manage just fine during laning phase when this happens, but I've lost several teamfights because my Q goes away and in the midst of all that action, I can't properly aim the stun.

It only ever happens after contact with at least one unit, but I can't get a consistent repro case. Minions seem to usually be involved in its disappearance, so you may want to start there. I don't really know what else to say about it. I've tried to figure out the cause on my own for several months, but it only happens like 5-10% of the time. This honestly feels like a pretty high priority bug and maybe it just hasn't been reported since no one really plays Anivia.

Anyway, I hope you guys can fix it so I can reliably use Anivia's Q.

While you're at it, can you improve her attack animation please ;)?
