More good news (can you stand it?!?)
The AI is now building ships with the Reactors and correct engines (although none have reached a point where they are building the medium sized reactors so I'm not sure if they'll use them - or how they'll use them). Carriers, kamakazi, colony and transports are all over the place and they are now being joined by attack ships (although poorly armed - but hey I've just started). It's looking promising

I will post all the new Data files and an AI folder tonight or tomorrow (when I get a chance).
Yay!
