Sorry. Yesterday, I had a bug where the player's save disappeared as the wrong file was distributed. I fixed that part.
If the save file has already been damaged, please follow the following process.
1. Go to C:\Program Files (x86)\Steam\steamapps\common\Temporis Arts\save\ (or game installation folder\save\)
2. Replace the MusicTemporis.dat file with the latest and largest file numbered MusicTemporis00.dat.
2-1. Do not use MusicTemporis10.dat at this time.
3. If you still have problems, try using older files more and more.
If it doesn't work out well, please contact me through the Discord channel, thank you.
