[When in multiplayer career, game is stuck on 'loading' button when going to match]

I've also had this. It gets stuck on processing when both players have clicked go to match.

[I can't connect to online game while internet is fine]

Friend trying to join my game is having the exact same issue.

[League Standings Incorrect]

I've just got the same issue, I will upload my save. The issue is with Benevento who have beaten Fiorentina in head to head and in goal difference, but due to being on the same points as Lazio as well it seems to have ordered them incorrectly and it was the difference between Champions League. Uploaded as "Network - Brescia & Benevento League Table"

[Player stuck in Trialists Team 1]

Uploading the saves to the SI cloud service. The names are "Network - Brescia & Benevento (v03)" and "Network - Brescia & Benevento JUST IN CASE", the saves are far apart though. The player in question is Josef Janás for Benevento/Trialists Team 1. We wanted to carry on though so the player was sold.
