Still having this issue, been about 5 weeks since I transferred. Other than this thread, I posted one on the Forum Bug Report forums and opened a ticket about the issue.
My character is broken. The API for at least several hundred players is broken. Surely this can continue to be escalated because whatever has been tried thus far hasn’t helped.
I’m especially concerned since I plan on transferring two toons tomorrow morning after reset to a new server. I’ll be unable to use any 3rd party websites on them going forward until this issue is fixed. It is unique to toons that realm transferred it seems. The API is broken, as mentioned above, to where any realm transferred toons are stuck in some state of limbo on the back-end, where, for example, there is no “class” assigned to them. It’s set “playable class” = “0.”
Here is the other thread I made about this: TBC Classic Broken API/Forum Characters
Please please please Blizzard, help us out here. I know you are short staffed but this problem isn’t just about “being able to post on the forums.” It’s the fact that TBC classic players are unable to use any 3rd party tools unless their characters exist here on the forums.
