Mr. Yang is not actually a Thailand NPC: he belongs to the old Shanghai area of the Chinese client, and his map (a Shanghai field) is one we have not brought into the game yet. He and the Shanghai quest NPCs around him (Chief Officer Chu, Officer Chung, photographer Cho, stall owner Yeo) are on our list of NPCs waiting for a home, and where they go is Mark's call, so this stays open. We have not finished checking the rest of the Thailand area for missing NPCs yet. If you know a specific Thailand map where someone is missing, add it here and we'll check that map first.

Thanks John! Mr. Yang's home is the old Shanghai, so we brought the whole area back rather than just him. He's on Xizhou Crossroads, out past the Shanghai farm fields. With him come The Bund, the Shanghai Airfield, Yuyuan Garden with its Adventure Arena, and the fields where the livestock roam. Chief Officer Chu, Owner Yeo, Cho the photographer, Officer Chung and the rest of the Shanghai locals are back at their posts, and so are their quests.

Getting there: talk to Spinel (World Tour, Lv20+) and pick "The Bund (Shanghai)". From The Bund, head west through the Outskirts of Shanghai, then the Northern Shanghai Plains and Hills, to reach Mr. Yang at Xizhou Crossroads. Spinel at The Bund flies you home again.

This is in the next update. It isn't live yet, so it stays In Progress until it is. Once it's out, please check: (1) Spinel's trip to The Bund, (2) walking out to Mr. Yang and talking to him, (3) the Lady Li / Owner Jang / Lady Jin shops on The Bund.

On the rest of Thailand: we haven't finished checking every Thailand map for missing NPCs yet. If you know a specific map where someone is missing, add it here and we'll look at that one first.

This is live now. The old Shanghai is back in the game: talk to Spinel (World Tour, Lv20+), pick "The Bund (Shanghai)", then head west through the Outskirts and the Northern Shanghai Plains and Hills to find Mr. Yang at Xizhou Crossroads. If anything looks off (an NPC you can't talk to, a shop that won't open, a map that won't load), reply here with the map and NPC name.
