also, when increasing teams you need to add additional info to a few other offsets in the EXE or the game will crash.... I know that reducing teams in a league doesn't require extra changes, unless there is a requirement from the game to use X clubs from Y division in a cup..... for example if FA Cup needs all 20 teams from EPL in it you can't reduce.... but obviously the Greek league doesn't need that and thee are no issues.... I would assume that a few leagues can be changed this way but you'd have to test and find out.... but don't try increasing or you'd have to amend the # of fixtures and rounds in the EXE itself which is a no-go
