Fixed a major issue with save files caused by the move to GMS2. This means that anyone who played this game for the first time on versions 2.05 through 2.06 will need to move their save data to keep it. There's a tutorial below on how to do this.
If you played for the first time on one of these previous versions, the save file will be located in the folder you installed the game in. The file's name is "sonic.ini"
Type this into your start menu: "%localappdata%\Five_Nights_at_Sonic_s". If the folder does not exist, just type %localappdata% and then create a folder with the exact name.
Move the save file into this folder. This will restore your save data if you first played on 2.05 or 2.06.
I'm genuinely sorry that this issue slipped by. It wasn't noticed during testing due to the weird nature of the issue. This patch fixes the issue and you should be able to enjoy the game as normal without losing any progress now.
