The only reasons why i still buy and play fifa games and i get this bug. Help?

So career mode is the only reason I still buy fifa games, and before i start my career mode, I usually edit some rival players just to increase difficulty level of rivals, and also I transfer players that are likely gone from the team or players already secured for next season from a club, for example Mamardashvilli to Liverpool or Kendry Paez to Chelsea.

I was doing this yesterday, and then it came to a point I was editing lineups, and the entire line up just froze. I wasn't able to move a player from his position, this is definitely a bug, and after spending hours editing squads, then for this to happen, I just wanted to break the game and never buy it again.

Has anyone experienced this bug? Is there any workaround? Should I just reset squads and not touch them? Literally the one reason I still buy this piece of shit franchise game and now it's bugged. Damn you EA
