We've managed to fix the problems with half/full time now and all the players' are reset correctly on screen. The other bug to do with the players' running out of the play area has also been sorted out, although I'm yet to make the changes to the code to stop this happening. I'll get around to it sometime this week.
I've also been playing around with the different team attributes. So now you may play against a team who are faster than you, run with the ball more often and have a stronger kick when shooting at goal. Or they may be dead slow, pass around a lot and have an average kick power - a bit like England in the World Cup !!
