I've played my first innings, batting in a T20. I had three of the stumpings I've been reading about. It doesn't seem like what I'd call a bug, more that by the time the animation for the shot has finished the keeper has whipped the bails off and there's no time to trigger a return to the crease. It feels realistic if a little frustrating mashing O while the batsman looks off into the sunset admiring his form like a golfer. A run out too where the batsman just didn't put his bat down despite having both feet in the crease.
Other than that, my initial reaction to batting is very positive. The shot variety is excellent, finding the gaps is easier. I was planning to go for a smoke at 10 overs and instead batted my entire innings. Now for a bowl.
Will be sorted! They are already tinkering away!
