I set everything up last night and observed the crash on May 15th when simming a season. The game didn't actually crash for me. It just hung on May 15th, so I had to stop it with the Task Manager. I looked at the rosters in MVPEdit and noticed that most of your minor league teams are filled with "x.x" for the player names. I did find that it is the same in TC1997, however, I could sim a full season with that mod with no problem. If I have time tonight I am going to try (and you may want to try this as well) to export all of the major league teams with MVPEdit and then re-import them into the default, out-of-the-box, rosters. This may not fix the issue, but it it will take one more variable out of the equation, so that every player in the game has a unique name.
