My guess is that he may have changed something and it caused a problem with the games simming.

Just checking, has JDB made a comment about this issue yet?

Could it be the AI is SHOCKED at one (or more) of the Championship participants and therefore is going back to game 1 of each league and reviewing results? *shrug*

Just throwin it out there...............................
