Interesting one after the latest patch. The AI will happily just drop the ball at their feet with a defensive shot and sprint a single.
The bowler is completely uninterested in trying to stop it. They amble over, do a slow pick up animation, stand still then throw to the keeper long after the run has been completed. Unless you have a close catcher in short mid-wicket/short cover don't try to come in and stop it either.
The AI has done it to me about 10-15 times now over two sessions. No way to stop it apart from slot a silly mid-off or similar into the set up.
Here are 2 examples:
Not sure if I'm willing to call it a bug. I mean, you can do this IRL, it is possible, but it all feels a bit cheap if my fielders are just going to let it happen without really trying to do anything. If it happened all the time, a close catcher in real cricket would be a must, but isn't. Idk, a bit odd all round.
