Your right that it's been a problem since DBC17, but it feels 10x worse after the last patch. In career mode, it doesn't matter what target your team sets in ODIs, the AI will chase in 30 overs. In my 16 team ODI league, since the patch 90% of the teams batting second knock down a 50 over target in 25/30 overs, irrespective and score/skill. I've had to stop playing these modes and stick to Ashes and tours. It's so annoying because team on team gameplay is truly a joy to play.
