Nostalrius Begins - Quality wow vanilla realm (1.12)

So, I went to org to accept the level 50 hunter quest (I'm currently 51), but the trainer isn't offering it to me. I also noticed he was telling my "I can not train you", even though he quite clearly can and does. Don't know if the two could be linked, but is it possible he doesn't see my char as a hunter somehow?

I tried relogging, tried deleting WDB folder, no luck. Is this a know bug? Am I missing something?

Patch 1.7.0 (ZG Patch).

As for the trainer saying he cannot train you, I don't know about this one.
