Can confirm this is an issue. I'm getting 4/5+ yellow cards every game and quite often a red card from a second yellow too.
I am not using any kind of unique tactic, just the preset 'control possession' tactic. I have made sure "get stuck in" isn't selected. Not sure if there are much other tactical changes available to reduce the amount of yellow cards?
I am not playing any differently to previous FM games and it's becoming almost unplayable now.
