Bots are stupid. All they know to do is point at the nearest target and shoot, or run for the nearest pickup that's in sight. They're great at getting to things they can see. But how do they get from room to room? If their health is low, how do they find their way to a health pickup? Well, Unreal generates a path network that connects everything in your level. That way, if a bot has no one to shoot, or is low on health, they know how to run through hallways to different rooms where there are goodies for them to pick up.
To start, click on the Build Paths button at the top of the screen:
Paths are automatically generated, connecting every player start in the level. You can view your path network by clicking on the black arrow that's at the top of a viewport and clicking on Paths, or you can just press the hotkey P.
Any player starts that are in view of each other should now have a line connecting them.
