I created a custom faction with custom colours, etc. Started a new game on large Map, played for about 150 Turns and saved. When I loaded the game again later the Primary & Secondary colours of buildings were reset to grey. So was the Secondary colour of the clothing. The Roof and Faction colours did not change.

I tried making a few new factions but the same thing happens. The Primary & secondary resets after a game save & load.

Anyone else seen this? I've got Ver.1.09, can't remember if it happened with 1.08?
