I am pretty sure the language barrier is hindering this conversation, but to say some things:
The issue should be fixed, although I will look at the code one more time to make sure broken saves get overwritten with a new. I know brand new saves get created normally now, but I will double check if broken saves get fixed.
As long as the Xs are displayed in the achievement zone, you will not be able to earn achievements since the game can’t save them anywhere. As long as you play any version before -3c, the bug will come back if you don’t have a working achievement save already in place.
