Well, they still there after 3 years of gameplay, 12 Toltayans ships, most of them Light Cruisers.
I thought they were getting the Ship Training Facility bonus, so if they can't then they are just doing an official visit to my planet
I guess the AI just left them there because it doesn't have any war going on.
One question:
Does the AI upgrade ships?
Will the AI scrap obsolete ships?
What about mothballing?
