But it seems to only be the phase of the Vale that characters who have started the 8.3 quest chain are currently using.
Because even the past version of the Vale is a different phase from what you see if you haven’t started 8.3 at all.
In the original version of the Vale for players (even 120s) who have not done any of the 8.3 content, he is appearing as expected.
I apologize if this issue has already been resolved, but if other players have the problem I had with handing in lore scrolls with Loremaster Cho, I found a solution. I was in the “phased” part of Pandaria and wanted to hand in lore scrolls on a 50 toon. Cho was in the seat of knowledge but wouldn’t speak to me. I went outside, to the right of Mishi, and clicked on Zidormi. She took me back to “old” Pandaria and I was able to hand in all my lore scrolls. Again, I am sorry if this is responding to an old thread, but I thought it might help other players who may have had the same problem.
This is generally the solution when someone needs to get from a “current” or “altered” zone to the original. Zidormi is available in places like Darkshore, Silithus, and others.
