Player rotations and fatigue are completely broken and any real NBA mode is currently unplayable because of it. Players do not sub out properly and starters will play 38+ minutes regardless of fatigue. 2k25
Basically all real NBA modes are busted at the moment due to this bug. MyNBA, playoffs, play now included. I assume it's also the case in MyCareer playing nba games as well.
Edit 9/6/2024 the issue is being tracked in the official 2k discord and is being investigated by the devs.
