Fractals instance bug
The way that used to be fixed, was to leave party and have them reinvite you. I do not remember if going to character select was required after leaving party or not. I do remember another situation where would have to guest to the server of the instance though.
Hope any of that may help if it happens again. Regardless, definitely send a bug report via /bug

This still goes on.
Whenever all the other players are from the same world, I can’t join their instance. The panel appears in a corner, set at level 50, and there’s nothing I can do to join them.
Leaving the party and re-entering won’t work. When this happens I call the instance ‘poisoned’.
I’ve lost several dailies because of these poisoned instances.
I just drag the window up and enter, even though it says your max personal level, it should be entering the same one. I know that is all it took for us. If it’s not letting you in at all, don’t have anything more to suggest :/
