What stadiums does it show on the fixtures screen? Is showing all Sydney? Some of the teams that have been downloaded especially the ******s have renamed the Sydney ground to their respected home grounds. Also check what ground you have listed against the country’s, this will help identify any errors e.g. Ireland have 2 grounds listed but one of them was a copy of Sydney (renamed of course) as that is the default stadium. Also the more stadiums linked to their country means more grounds to play on but it is randomised, so you cannot choose what stadium to play in which is a bit annoying. I think only in casual mode is where you can choose the grounds.
Another thing when you finish your game does it registers the correct details of the result? Or does it show different teams with your result and then show’s your fixture that you just finished as not being played? This has happened to me in the WC 50 overs competition.
