Thanks for the speedy reply Gaunathor. I wanted to change the type of mine output so that I could derive benefit from the asteroid mining when I was doing an all labs game. To speak more clearly, currently in an all labs game I can see no benefits coming in from the mines. I checked if it benefited ship building, social projects or research and it did not - (because I do all my ship and social projects using research focus).
I had hoped that it would be possible to change the xml file to adjust the output from the mines from pure industrial to (industrial/research). It's no huge deal, but I just hate to have something built into the game be unusable (and the mines look good on the screen).
Since I have your attention for a second, I noticed that you referenced the file in the DA folder. I am playing TofA (Ultimate Edition) and playing TofA. Does your reply indicate that many of the base game files used in a TofA game are actually located in the DA folder? This seems a bit strange to me, but correct me if I am wrong but did Stardock do a tiering system where the game backwards looks at mods/tofa/DA/DL when selecting what to load?
