P0-B5: Part 1287: Debugging, Improvements

I have done some further testing on the AI system, and despite some minor bugs, it seems to work well.

I have some more features to add to my current AI system (Including smoothing out the navigation points), but after this, I want to try to replace the existing AI system with my new system.

I also have a lot of playtesting to do within the cities, but other than that, most of the work for B5 is done.
