Seems like Raptr doesn't track Diablo III anymore. No gameplay shown on your website although I played for hours.
Do you know if this happened since the recent patch for it?
That could be the reason. I can't say for sure because I recently started playing again with the release of 2.4.
Also, there's a bug atm, where you manually have to kill the task (diablo3.exe) in order to quit the game. Really strange..
The manual kill to get out seems more like a Blizzard issue. However, I'll see if I can't get QA to test Diablo III to see if any changes have been made.
