Spells: Spell sounds are all wrong from recent patch...

[The Thread Necromancer]

Logged my druid today.

Noticed that my frost nuke sounds like a buff...
my sup. camo. sounds like a root...
levitate sounds like canni...
the list goes on and on...

I did a search through the list of changes in the patch, the word "sound" doesn't appear. I'm assuming this is a bug of some sort with the patch? Confirmed this with other people as well -- spell sounds are sounding like other spells.
