all star game bug

After i played my first all star game on my sophomore season, from 41 minutes it went down 14, for people had the same problem and found a resolution, please tell me how

As you've noticed, it's a bug. A bug carried over from 2K10 to 2K11 and now from 2K11 to 2K12. As far as I know, there's no solution. Just play well to get your role and minutes back up, that's probably the only thing you can do.

or just use cheat engine or tsearch to put your minutes back up
