Does this require a new game? I installed after completing vanilla but they aren't showing up. However if I go to a new game and preview, the map does show hostiles. Is there a way to force a refresh to trigger them or am I SOL on the existing game?
You need to explore the map for new enemies to spawn (black completely unexplored terrain). Explore around your base and then let them sprawl and built outposts closer to your base
