FYI, already found a couple interesting things:
- Due to ship cap scaling, some of the ships are created with more than max-health and that health is then corrected downward during game-start. That cutting down of health to MaxHealth appears to have been triggering "angered" status on the microfighters. Read into that whatever you will.
- AI Fortresses and Melee-Guard-Posts were being counted as threat because they can move, despite not being able to go through wormholes. I'm tracking down the critical point of this one so I can add the check on can-go-through-wormholes. I suspect that a lot of the threat we're seeing is the former guards of the melee guard posts.
