I've added my own club to the Conf South, peachey and keen.
Then I've added a logo to the club and added the code to the config files, restarted a game and it appeared at the top of the screen no troubles.
But for some reason it keeps disapearing and reappearing. I've noticed that after I installed the English super pack Basingstoke and a couple other team's logos disapeared and came back.
BUT I added the club logos for Australia and have never had a sniff of a problem with them.
Any ideas? I've noted some other people have had similar problems, but with clubs they've just replaced the logo for.
