The Problem:
I have bug quest chain in Icecrown. In
Argent Crusade after ques http://www.wowhead.com/quest=13086/t...ine-of-defense
After changing location environment , and sent you to a camp near the Argent Crusade where are located NPCs: Crusade Engineer Spitspatritsk; Crusade Architect Silas; Father Gustav. They dont give me any quests.
I can not continue on the chain of quests , and get the rest of the quests in the location.
How it should work:
NPCs: Crusade Engineer Spitspatritsk; Crusade Architect Silas; Father Gustav, the should give me quest
namely here these: http://www.wowhead.com/quest=13135/it-could-kill-us-all
http://www.wowhead.com/quest=13130/t...d-a-revolution
http://www.wowhead.com/quest=13139/i...t-of-northrend

How to reproduce: Please, help. Maybe you need to roll back the character? Some think 3 hours. Perhaps changing environment is the bug. In all other normally done, and I came out like that.

I cant do quests in this location and improve reputation with a fraction. A think i need only character rollback say like 3-5 hours at. Pleace help me.
I'm stuck in this location , and I can not go on playing.
Thank you for understanding , waiting for an answer .
