UPDATE! (1/3/2013): Today's patch should contain a fix for this issue.
It has been brought to our attention that there are two issues with the latest update.
The first is regarding the tutorial. We now know exactly what is causing the issue and it is, basically any character that is made after yesterday's patch will not be able to progress past the first mission. All quests will be greyed out and you will also not be able to accept the Guard test. We are aware of this and we know where it is failing.
The second is an issue that we have heard about regarding the new Phoenix items and enemy in the Kunlun Mountains. We are investigating this and have top men on the case. Once we have a more definitive solution and know what is going on with those items, I will edit this post.
In both cases, we are in contact with the developers and are working on fixes for these issues to make them available as soon as possible.
Thank you all for your patience while we work to resolve this issue. Please refrain from sending in any tickets regarding this issue as we are aware of this and are working diligently on fixing it.
