Wotlk: Unable to progress quest chain after faction change

I recently purchased a battered hilt on my alliance character and I am unable to pick up where I left off on horde side. Submitted a ticket but the GM had not heard of this bug so here I am.

The steps I’ve taken are as follows:

  1. Started up the Battered hilt quest chain on Atiesh alliance. (Char name Ghostcatt)
  2. Picked up the quest Tempering the blade, did not complete this quest.
  3. Used a faction change.
  4. Logged into Atiesh horde to pick up some gold from an alt.
  5. Server transferred to Grobbulus. (new charname Ghostkat)
  6. Flew over to Myralion Sunblaze in Icecrown to attempt to pick up where I left off.

This is where I run into the bug. From my understanding, your questline should automatically carry over onto horde side. However, Myralion Sunblaze offers me no quest or dialogue option when I click on him.

ps. Why is there an option to add a link to your post, if you get a popup that tells you you’re not allowed to add links to your post?
