P0-B7: Part 1379: Debugging, Improvements

I believe I have fixed the issues with the AI on changing zones.

The issue was that the AI wasn’t paging to the client when the player left a zone and then returned.

This required some rewrites to the server-side code, but it seems ok now.

The server AI is a lot more solid already, the next step is to run more tests to see if I can spot any additional bugs.
