I think generating flags for each teams with CM fixed the issue.Lastly, I noticed that with this update you fixed the black fan scarves, awesome! Did you use some automation tool to do it or did you create all the files manually?
I believe some default CP seasons also have this problem such as 09-10 and maybe WC2018 so it would be great if we could fix it too.
Besides, I encountered a problem with tournament dressings assignements. Files were not assignated for tournaments whereas their names did not seem to be the problem.
Have you any clue ?
