Just to clarify my last post regarding game speeds, this happens only when you select "Quick Match" option. If I start a New Game and select T20 format, the game plays fine. But the game stutters a lot when selecting Quick Match (especially when the ball goes into the outfield, the game slows down a lot).
Also it seems that bowlers do too much running in the outfield. I had a dab shot played on the off-side. The bowler was chasing it till the ball had almost reached the boundary line even though there was a cover and deep-cover (who stood stationery).
Another thing I noticed is that the squads are completely messed up. When selecting "Auto" on lineup selection, it only selects 5-6 players from the list and OK button is enabled. If I press OK, it adds all the old (retired) players in the playing XI (who are not even in the lineup selection screen). Confirmed this for England (had G. Thorpe playing a T20) and India (Azharuddin and Raju added automatically).
