Problem with Gelkmaros final campaign mission

[Sokar 2]

Cant finish last mission of Gelkmaros campaign: Quest for Siel's relics, need to talk with an npc that appear only when the fortress of crimson Temple is under asmo control... but in over 3 month asmo never take it can I ask why? It is too much difficult to take?

Hello,

As the quest can onlu be done this way, we cannot actually interfere in it. The players should just go for the fortress, we can't just take them and bring to the siege.
