I can't commish full-time, but I think the big problem is with irregular characters in city or team names. São Paulo and Kópavogur are two I know can give the game issues at times, especially with logos/jerseys/caps etc. I think we need to change any team name with those characters to just a regular "a" and "o" if that's possible. When i went into the saved games files in OOTP15 I saw that it only imported a few caps and then probably got stuck on some weird character. I deleted all the logos/jerseys/caps files and then tried to import again and it worked.
