I was in the game lastnight at reset on Android Mobile and when it reloaded my game Nexus was not on the map thought ehh it will be there in the morning and I went to bed and it is still not there. Reloaded the game a dozen times, uninstalled it reinstalled it and still no Nexus. Loaded it up on Steam and its not showing there either. Am I missing something?
As mentioned here, you need to finish other kingdom quest first
