Hello,
I am receiving reports that player progress has been reset following the 1.1.0 patch.
To resolve this issue, please try the method below.
1. Go to the Documents → Treasure 'n Trio folder.
(Or the game installation folder → Treasure 'n Trio folder)
2. Copy the file SaveGame.txt.
3. Go to the folder C:/Users/(username)/AppData/LocalLow/TNT/Treasure 'n Trio
(AppData might be hidden.)
4. Paste or overwrite the SaveGame.txt that was copied.
5. Run the game.
I apologize for the trouble.
