Well the last patch did make fielding pretty good. One of the few areas that they hadn't fixed was fielder lag after a dive-stop or tap-back. This seems to have been an area that's gotten worse in this patch.
After an overthrow last night, the ball slowed in the outfield and I'd gone from a single to running for 3, I looked and saw an AI fielder just standing there 20m away stretching. Then he jarred back to reality and jogged over to get the ball and throw it back. I ran 5.
Then I noticed when I bowled, many times when the AI batsmen had just hit the ball gently or blocked, the infielders and bowlers would just stand looking at the ball till it had rolled off the pitch block. Overall fielders are lagging in response.
Also, for us semi-auto fielders, something is still unfixed for months now. Every now and then, when you go to do an L1 and O or X, or an R1 and O or X, sometimes it doesn't register and you keep repeating it, but it won't throw back in, giving the AI an extra run. You have to stop trying to throw it back in and then after a second or so retry and it'll throw it back in. This seems to happen about every 3-4 overs.
