Finally picked up the game since the update, played about 5 or 6 matches in a new ML, can't tell the slightest difference in fouls, GKs, or scorelines. It all seems exactly the same as before to me, except that bizarrely the update changed my speed to -2 (?????), so I changed it back to -1 as I spotted it on my 1st match. I can only tell rosters, formations and starting line-ups have changed (not always correctly), as for gameplay I can't tell a difference at all.
The best thing, which is definitely a big fix, is that there aren't a lot of great players as free agents anymore, so I really have to spend money I don't have and end up not changing my team much on the first year. Until now I could replace half my team almost for free on the first transfer season...
