First of all, is there a difference in outfield speed based on the stadium?.
Secondly, if there is, it should be based on grass type, which is visible while selecting the licensed stadiums.
Thirdly, you can still change short force mid way during the game.
I haven't noticed difference in outfield speed, unless it is a smaller ground and hence it reaches boundary quicker in comparison.[DOUBLEPOST=1560020506][/DOUBLEPOST]
If it is a no-ball, the on field umpire will pick it up.
It is always called correctly in game, as designed.
