I just made a quick map with a few of the new planets, stars, uncolonizeables, etc. A good number of random planets too. Might be good to investigate the new dlc or it might be sh**. Either way feel free to download from the link below

EDIT: I should add this map will need to go in your
C:\Users\<User Name>\Documents\My Games\Ironclad Games\Sins of a Solar Empire Rebellion\GalaxyForge
directory. It will appear as a galaxy forge map. Feel free to tweak it to your liking.
