PlayerPrefs on Windows 8.1

Has anybody else had an issue with PlayerPrefs on Windows 8.1 ? I’m using PlayerPrefs for saving HighScores. During the game PlayerPrefs seems to work, but if I restart the app all saved stats are gone. Why?

Maybe you don’t call PlayerPrefs.Save?

Yeah, you’re right. It works perfectly now.
It’s weird because it seems to work on other platforms without calling PlayerPrefs.Save().
I really appreciate your help!

It’s a known issue. Don’t use the Build and Run command from the Unity editor.
Use Build.

Then run the game from your Visual Studio solution.
