I remember, when I first played SC2 - the DOS-version of course - there was the option to sell an egg case fragment to the Druuge, and they offer you refilling the fuel tanks to maximum.
So... I placed only high-ef-fuel-systems in my ship and let them refill. After this, I remember the Druuge to be very angry at me .. "Our fuel tanks are almost dry!!" .. BUT they made the deal! After selling the fuel in the space station, you never will have any problems with money again *g*
But somehow, it doesnt work in the UQM. But why? There was an extra dialogue with the Druuge (so TFB did even consider this option). Or am I doing something wrong?
