Thank you for your work!
I didn't install previous version, but when download 1.21 I got same bug as Mashinrou, deleting folders doesn't seem to work, it apearring every time т^т
Oh no, It's caused by save data error, It could be fixed by deleting some where like
C:\Users\User\AppData\LocalLow\AoiSora_3D\DesktopRushia\PlayerCollection.txt
but that would lose all the save data. sorry for the bug
Unfortunately, it doesn't seem to work..
