Classified some of the nodes as spawn points (little red nodes in the corners) - this is where the Agents will re-appear after they die.

Also classified some of the nodes as ‘room centres’ (blue nodes). The AI search to these when they have nothing else to do. I thought this would be a bit more like how a human player would play the game, you generally search from room to room when you can’t find anyone, and probably wouldn’t just wander into a random corner.
