As it has taken me so long to get a pc back up and running... weapon and engine techs have been removed. Just wanted to get a working 0.3 up, download the mod here:
37mb zip**Shadow and Vorlon hulls**
For anyone who wants to play as the Shadows or Vorlons, try extracting
this file and putting the logistics.xml file in your ...\GalCiv2\Mods\Babylon5-03a\Data\Techs\ folder. When you start a new game and get to the race config screen, be sure to press 'clear' and the hulls should now work.
