There appears to be a bug with the game reading the weapon_list.xml file. In the game, I noticed when buying new weapons that the range listed in the description appeared to be a lot less than it should. I dug out my old Privateer Playtester's Guide and compared the values it listed with the ones listed in the game, and noticed an interesting pattern. The ranges seemed to be almost correct, except that the last digit was missing. I went into the weapon_list.xml file, and added a zero onto the end of every range, and it fixed it. So apparently, the when the program loads the values from weapon_list.xml, it ignores the last digit, for some strange reason. Incidentally, this is not just matter of the game incorrectly listing the number, but interpreting it correctly when you're actually using said weapon. I tested it out in combat, and as far as I can tell, if it says 460 meters, that's the effective range of your weapons when you're out in space shooting at another ship.
