I met this bug too. Sorry I'm not an English native speaker so I can't exactly understand you explanation.What means a fresh save or included save？I entered 4.1.1version by an old save and created a new save and entered again by the new save. Still met this bug.
The game comes with 4 saves already made that are at several points during the game (updates and info on title screen for full details). You need to use those or start the game from the beginning. If you use a save created in an older version, it will be missing information from the latest version necessary to run properly.
Oh no...... TAT QAQ 55555 I will cry. I just downloaded complete 4.1.1 windows version and found the 4 saves. But they all seem like are at the former chapter. I have already been HR 22 but the highest level of Mila in the 4 saves is 14. Are there any solutions to rescue the saves in older versions? TAT
