@Neo_GeoI've just started a save in the Swiss leagues as well. There's 3 promoted teams if the lower league team wins the playoff, confused me for a while until I realised the Super League was restructured from 10 to 12 teams. Did you get the choice of Chiasso, Kriens and Rapperswil?
Edit; I've just taken over Rapperswil-Jona (excellent academy coaching the only reason) and I've just checked the affiliates. They have a Senior affiliate link in Grasshoppers and there's a clause stating "The terms of this deal will prevent Rapperswil from playing in the same division as Grasshoppers". There's no option to negotiate or cancel the link either so I'm assuming this would prevent the club getting promoted unless Grasshoppers manage to get relegated in the same season?
