Also happened with me as well. Basically ruined my whole main save. Played my 5 star player in the right position every game and now he is just mad every game because I play him in a weak position(its the right one). I built the whole team around him and now he is spreading bad morale over on the whole team, we are loosing every game and the whole save is in shambles. Also a bug I noticed is that "fake" promises, that never got made suddenly appears on my players during the season and makes them unhappy. Morale is such a big factor but its so bugged this year makes the game unplayable.
