Okay - I've made a big mistake. Saved my game at the end of a session when I'd been offered a job overseas. Didn't really want it, but was curious, so agreed to accept the job at the end of the season, after saving, and then put the game in holiday mode thinking I could come back after I'd taken over and see what the club looked like.
Problem was, whilst in holiday mode, the game automatically saved over my 3 save games every hour. Whilst the oldest of the saves still has me with my old club, it contains agreement that I will take over at the new club at the end of the year.
Is there any save game editor that will allow me to remove the flag that says I have agreed to take over another club at the end of the season? I don't want to move to Belgium...
