I am at the end I think - mission is called Salvation. I cannot reach the planet I need to take over for some reason. There are not systems or resources that can exdend my reach. Even using cheats that get me every tech and bulding ships that should be able to reach the destination it still says that I cannot travel that far. I am puzzled as I have tried numerous ship configurations and no combination will enable me to travel far enough. What am i doing wrong?
