Trouble at Greystone keep?

Courier Gerald not showing at the location he is listed as being on the map. I’ve just finished the proudmoore questline and supposedly following the online guide I can take the gryphon back to tradewinds market and pick up another quest line from this NPC. I’ve tried logging out, leaving the area, even doing the four world quests thinking that was keeping the phase out of sync or something. Any ideas?
