[Darkness Falls: They mostly come out at night...]

That means you have 0 traders on your map.

 

Make a new map or use one of the included ones. It's really, really annoying. I know there's a 3rd party RWG tool.... I'm gonna look at poking that and see if I can edit it to include compo pack and DF specific prefabs.

 

when I make a new map always get a null message

Is there any solution?
