Well yes, in testing. Sorry if this is redundant because you already seemed to know, but one of the reasons I know of for skins and outfits turning one colour or devoid of light is that the CC skins and outfits they were created with does not exist in that particular player's game, and is substituted with nothing. So a wild guess is if there is a technically skilled player that knows where exactly these 'special outfits' are saved, maybe an eradication of the CC there as well would help, after clearing your cashes of course. I have been told that the mod Master Controller can be used to change outfits:
