Visual/audio bugs after recent patch

Didn't happen as often as of right now. Examples:

1. Karthus "dance" (where he sings to his mic-want) uses Anivias screech.
2. Fiddlesticks hands have green effects all the time (it should happen ONLY when he drains)
3. Lots of semi-invisible projectiles. For example: Jinx Zap [W] has 2 animations. 1st shows where it'll fire, second is projectile. Right now it lots of games you see only projectile.
4. Lots of invisible projectiles that don't use other animations.......... . . . . . ..Nidalee spears/Jayce empowered Q..

And then as a bonus LoL client often crashes at loading screen asking for checking network. Which is very easy to fix. But still annoying.
