When I made new factions before, I'd let the main color for their roofs and clothing be the faction color. Now when I make faction colors I'll sometimes link them all into the shieild of the faction. Such as the red shield with golden dragon on it. I'd make the faction yellow, and the roofs a dark red, and the outfits a dark red, and a light red.... When I shut the client down, and start the client back up again, My roofs are yellow, and my clothing is yellow and bright red.. effectively changing my faction's appearance.

This has happened nonstop with new factions ever since I've bought the game on steam.
