WotLK Im stuck in party with no one

[Piposlavko]

Hello today i queued to RDF and it found me a dungeon dead mines and after i entered my character couldnt move and couldnt move my camera or log out or exit the game so i did ALT F4 and now im stuck in dungeon party with no one and i cant leave. If i enter to nearby dungeon by a portal and then leave i will appear on the place where i was queuing to rdf last time. If i try to invite someone to party it says that im not party leader.... im playing on lordaeron alliance my character name is Piphanus lvl 19 warlock

I've also had the same issue as the thread creator. As I can confirm what skullatbash said, it does work.
