I'm currently pursuing the 'Memory of the blade' quest. And I'm told by Shani to talk to Zoltan about the silver sword. I found him at the Hairy Bear Inn a few times before but now I can't find him no matter at what time of the day I enter the inn. What are the other possible places that he can be in? The map does a poor job of pointing to an NPC's live location as it's always pointing to the inn even when he's not in there!
I remember that I've also found him in the room where Vivaldi (the long bearded dwarf) stayed. He seems to wander between that area and the inn.
The wiki confirms:
Later in the game, Zoltan can be found wandering around the Temple Quarter (roughly from 8:00 a.m. to 8:00 p.m.) and, if choosing to side with the Scoia'tael or take the neutral path, in the Old Vizima. He also often spends time with Golan Vivaldi.
