I have an older save from the dupe beta but replacing data.sav didn't fixed the issue, it only restores my settings and stats until that point promting me the message that the save was from a previous version. Maybe the save was corrupted because I didn't replaced or resetted objets/events on the latest save (That last save has an endelss string of NUL text).
Maybe the best thing will be to just play in the old save and lose several days of progress, better than starting over again. From now on I will do a backup of the save files just in case.
