Ok, there is a simple fix to this for those that completed the OP timeline, but it will take time...
First, recopy the toon from live to reset the toon to 92, then use mail item (which I got one today) to go to 95, and then go do the questline again from start to finish...
Or take the advice of someone doing the quest, first go to Sleeper tomb and clean the zone out, then go to Wurmbone Crag and clear the zone, then go to Wurmbone's End and clear zone, then hit chelsith. Seems that is the quest steps, and if you want info on those steps feel free to look it up on those related topics.
