Next Car Game has changed its obviuosly placeholder name to normal name - Wreckfest.
So, main executable has also changed its name from "Next Car Game.exe" to "Wreckfest.exe". So, now Raptr doesn't detect the game
Path is the same, only executable changed:
"gameexe": "steamapps\\common\\Bugbear Entertainment\\Wreckfest.exe"
Reported the issue.
