Holding onto Ball In Ruck - No more Penalties / Match Difficultly and challenge

Hi there guys. I don’t notice anymore ruck penalties when playing on PS4 when I press square button and hold onto The ball when tackled or try to steal the ball. I think since the patch the referee does not issue anymore penalties. In RC3 this was always a penalty and infringement. Anyway I think this is a patch issue thought it was happening when RC4 game was first released. Also the patch changed the difficulty in the game. Even on hard difficulty I been finding it too easy to win games. Before the first patch Matches were quite challenging on Hard even against sides rated below your team. For example - struggling to beat Georgia rated 69.5 as Wallabies in World Cup. I think the issues are the adjustments made to fatigue and Ai does not substitute players unless injured. I have found this in Rugby World Cup as Wallabies and Super Rugby playing as Reds. Anyway just a few points here as I haven’t been playing matches a lot due to creating teams last few weeks.
