I just checked WnJ and central hub is in Wasteland.
Maybe i got this wrong but every seed i have used or made this update has the 0,0 hub in wasteland , sometimes the biomes surronding it are not wasteland but the centre is.
Just using a random seed and looting the central hub straight away doesnt seem a option unless your prepared to die alot, i think its a case of finding a seed with mini hubs/towns and crossroads that are in friendly enviroments in creative and noting the coordinates and then starting a new suvival game or maybe leave out creative and work on finding smaller towns and crossroads instead of attacking the central hub straight away
