Missing NPC on Onixia server

I recently noticed that the NPC Kania seems to be missing from Cenarion Hold in Silithus in the Onixia server. I've checked multiple times, but I can't seem to find her anywhere in the area. She sells the Formula: Lesser Mana Oil wich is a cheap one to craft to lvl up.

I also didn´t saw any Formula: Lesser Mana Oil at the auction house.

Am i just blind? :D

Onyxia has yet to reach the patches that add those two things to the game
