BLIZZ FIX ZF!!!!

Hey Blizz third day in a row now I got random group for ZF and all the mobs and bosses just disappeared. Cant find em and when I leave the group and re q i get stuck back in the same ZF group I just left. this has happened more then several times now since 3 days ago, whats up with ZF?? Got it to fully work once last night around 4am, but aside from that group yea all them dont work >.>

Are my groups missing some summoning thing? or is it rly a screwed up glitch? Plz fix or bump me outta the 45-50 level bracket so i can continue leveling without questing. ^_^
