After mucking about with V1.0 for a month or two, I finally upgraded directly to 1.4x. The new changes are great, but did they put some sort of limit on the Sensor range your ships can have? I have a ship with a sensor range of 37, but the actual sensor range is about the same as your Flagship you get at the start of the game.

This happens in my old savegames as well as with any newly created games. I suppose I could get eyes of the universe... never really saw the point before...
