Already started Get Junior quest when I noticed i forgot to talk to Zoltan to start the Gwent card quest. Nearly pulled my hair out of my head looking for him when I suddenly noticed he was spawn bugged at the Rosemary and Thyme front door entrance. Had to move around the door until I found a interaction zone where i could get a cinematic conversation with him and move him out of the bugged spawn area. Anyone else get this?

Nope :| I guess you were just unlucky. Weirdly enough, sometimes NPC get stuck in the current cersion of the game. Happened to me while I was helping Triss. Usually it is enough to load a savegame, or load an earlier savegame. Automatic save points, in my experience, are a good source of a safe reload :)
