Confirmed 3 new locations for her to spawn. West of bridge (-986, -1842) spawn. Both wagon static spawn points (-1393., -2351) and (-1253, -2325)
So that's 3 static spawns along stair wall (2 right and 1 left facing stairs), 1 under bridge north of stairs, 1 west of bridge along water edge, 2 spawn points east of stairs (1 in each wagon).
