Cold Storage Cross-Server Issue

[Eiria]

In attempting to join Cold Storage on the cross server today, it had me join an "in-progress" group that had already Wintermane and were instead staring at the secondary summon area. they did not do so, and the party collapsed. i left and once again attempted to join a Cold storage party, Every new attempt to do so put me back into that partially completed instance. On the fourth attempt, the group actually summoned Kaari and killed it, but now i can't go back in to kill Wintermane for the quest i went in there for in the first place.
