Not sure why is does or doesn't but I was able to save my first race, and it shows up in the factions folder, but i created another 3 and started + saved a game. Upon reopening the game they are gone. I tried again and this time had the factions folder opened, and they never get saved in there. If i copy the race that did save and save it it will make create another file, but if i edit over it and save it it will not.
Any ideas/ anyone else seen this?
