WotLK Stuck in invisible group ?

[eversongforum]

Happy holidays everybody,
something happened with my mage today :/. After a rdf hc run (in which i didn't receive EOF btw) the character seems to be stuck in an invisible group. If i want to queue again it says that at least one member of the group didn't accept the invite. If i try to invite the character into a group it says that the character is already in a group. If i try to invite somebody else into this "group" it the server answers that this person is not in my instance.

What i tried to far:

-relogging
-reload
-unstuck
-killed the character
-deleted wtf and cache folder

Nothing seems to fix the problem. Help!
