Dynasty Codebase Error

I was successful in my 1st Season in Dynasty Mode. But when it ended, i only have 1 player retired and it was Theo Ratliff...Just right after the 2nd season started, i decided to get rid of those generated rookies and i did it changing their original team to 32 to make them retired players....But then i noticed that there are some players gone like Omer Asik, Alex Ajinca, etc. More or less 20. I ignored that and continue playing without the generated rookies. Now i'm about to start may 3rd season offseason but when i simulate the Mock Draft Sched error popped out. What i'm supposed to do? And what i'm gonna do with those players gone to bring 'em back to the free agent rosters?
