WotLK unable to change faction

[Dralanne1]

okay, so i decided to change faction, and now for some reason i cant.
i bought it with points, and whenever i try to change faction(i just randomsize apperance) it says - could not change race for character... i tryed alot of rifferent looks and still the same.
i figured this might be due to wod models, if so, how to disable them?

EDIT:
it seems that its a visual bug, when you change faction, it shows that you didnt, but in fact you did...xD
logged in and its all good.
