Different leagues loaded? Maybe they were regens?
Probably the first one is the more likely.
Who knows, different leagues perhaps.
Weird actually.
Exactly the same leagues picked...and they appear in the editor. Some of the people not appearing are in leagues I picked...
DB size?
Very unusual. & what Athe said, it could be the Database Size.
Actually, did you update the game and after that the staff originally at the team were released or something?
