Critical bug, can't advance story line

Quest line: Magwytch Marshes - Main quest
Belly of the Beast
Talk to Oisin McAvoy

The NPC outside the entry will not open the gate to the site of power. Keeps saying that factories need xyz
I have completed it all (obvious as I wouldn't have the Belly of the Beast quest if I hadn't!)
I spoke with Nicholas and handed in, he sent me to see Oisin.
Nothing. First I though perhaps there was a gear level lock on top, but now that I have managed to raise my gear level over 70.. still nothing and I can't get it higher than that really. Other half has completed the zone with less gear level so it can't be that. Please fix this. I can't do anything now...
I have even attempted to reset the realm, no effect.
