Posted list of UWPs in the same thread as the map in case anyone else wants it.
As for updating to 1248, I dont have any 1248 data. If you can send me the data I should be able to, BUT, it may take a while. Its very tedious and I kinda want to redo Diaspora, Alpha Leonis and Solomani Rim in 1201 for my own campaign.
The UWP list I used came from Zhodani Base who claim it was originally from GDW. I dont know if it matches with 1248. This map was made by my best mate to see if he could. He is showing me how to make them myself, so hopefully there will be more on the way....
