A small question

[Radical Batz]

I notice that in the original game maps folder there are a few extra files, cache files and nodes files as they are called. I know how the cache one appear and what it does. But how does the nodes file appear? It obviously has something to do with testing the nodes for the enemy.

Yes, it appears when you made pathnodes for the enemy in the level editor! that file should be there I think! I have one too.
