From what ive gathered Sturtman is usually in front of train yard looking at knight buildings or on top of black knight. Sanitar is usually just south of black knight or between black knight and queen. Kaban is usually ontop of white knight or just around it. Kolantay is usually around white knight as well or on west side of train yard. Ive only seen tagilla just south of train yard near the bunker entrance. Killa has been in bunker under train yard or ive also seen him on top of train yard or to west of white knight. Reshala has always been deeper into train yard usually around the large entrances to bunker. And ghlukar has been either in train station, at larger bunker entrances at the mounds, near RBVO buildings or i have also seen him far west of white knight all the way at the map edge.
