NEED HELP WITH UPDATING/ADDING TEAMS

Hello. This question is for anybody with some experience with swosfff swos editor 1.3.
Does anybody know if the game actually allows additional teams to be created?
I´m doing so with editor 1.3, but the game still crashes at the end of the season.
Is not a problem of general team number, index number or country number;
and i´ve fixed the number of teams in the teams per league dialog box.
Suggestions welcome...

Your better just not adding extra teams if anything edit an existing team to many crashes on swos and
no one seems to know what or how it is caused.
if you start messing with swos something will go wrong it always has.

How sad is that. thanks anyway.
