I need to fix AI before posting the finished map.

It's surprising how long the list of requirements for map publication is on this site.
I'm attaching a map in development. The problem is, the AI is progressing quite well throughout the tech tree, but I can't get it to build secondary bases. It refuses to expand. It builds mines, but doesn't send workers to them. It builds new miners, workers, and main buildings, but refuses to build anything else nearby. I've tried various options.
Currently, the AI is building its base with its main production building. And towers. They're on the list, but there's a condition it ignores. I moved it up the list to ensure the AI expands. But again, it didn't work.
