I'm enjoying the game (only just finished my first season though, not sure how you lot manage to play so fast or so often!) but there have been a couple of annoying things recently.
I wouldn't recommend turning off the highlights as the game totally makes the score up as it sees fit. The first time I did that, I won 1-0 but suddenly the game thought it had finished a draw. It was quite late, so I assumed that I had just missed the equaliser, but it happen again the next game when I scored a late goal to salvage a 1-1 draw (the text commentary even said that I had snatched a late equaliser) only for the game to try and convince me that I had lost 2-1 and had been 2-0 down at half-time! I won't be doing that again.
I've also had a bad experience with promotion to the Premier League. Despite winning the Championship by the end of March, the game flatly refused to consider me a Prem team. My scouts were still recommending average Champ players after the season ended and my chairman refused to release any new funds so I was stuck with £0 transfer budget and maxed out wages (I couldn't even offer my assistant manager a new contract) for the first month of the transfer window and was forced to watch as all my transfer targets moved elsewhere. It has really dampened my enthusiasm for the new season
