Eins stand under the tree near docks. Go into the port, then turn south, you'll see him. White hair old man, he ia marked by yellow exclamation mark
The only person by a tree is Shirinsya (from the Brexeet Isles quest) and any characters you have to interact with now have a yellow exclamation mark above them.
Two days later and he is where you said, I heard the first release of the update was bugged, who knows, anyway thanks for your help.
