All the random christian CoA are colors 6, 8, 2 for me. Also they keep changing every single time I start/quit the game. For example, I can be playing as any character, save the game and exit Crusader Kings 2. The next time I start the game and load the savegame all the random CoA will be different, to include the one of my dynasty. They keep the 6, 8, 2 color scheme, which is applied to 19 out of 20 christian coats. Muslim emblems seem to have the same problem but with three different colors (two of them are white, one is either green or yellow). The randomization seems to happen on the game initialization, meaning that the coat of arms are generated once a session. All the savegames "receive" these new randomized coats of arms that are displayed in the start game map, so every day I have different coat for my dynasty. wth
REALLY UGLY.
Game is unplayable at this point. Hooray patch 1.06.
