Error: The game can't be saved

Hey guys,

Just returned to the old days and installed my 1st FM, and now have an issue:

If I just begin a game it works fine, but if i make a change in "Data editor" when a start a game with those changes applied everytime i try to save i get that error "This game can't be saved";

I know someone will say "so play without changing anything", but i wanted to make things more interesting for me, happened to anyone? Any solution?

Thanks.

does this on local saves, try saving to the cloud
