All settings and configurations for the game are saved in a seperate hidden directory on players' PCs, this means that when troubleshooting an issue, simply uninstalling the game will not delete these settings and issues may persist if the issue is with these settings.
To reset your user settings for the game back to default open windows file explorer, or your start menu and type:
%localappdata%\yakisoba
Hit enter and a window should pop up with a "Saved" folder inside of it, rename this folder to something like Saved.bak and thats it, your settings will now be reset to defaults while also keeping a backup of your old settings and log files in case they are needed for further troubleshooting.
