title: Error trying to register game achievement: The given selector string \"game:points\" is invalid
body: <p>I keep trying to register a Facebook game achievement (having successfully registered two others previously for the same app), but I am now getting this error:</p>
  
  <pre><code>{
    "error": {
      "message": "The given selector string \"game:points\" is invalid for Ent with ID 10150677676736030.", 
      "type": "OGPropertySelectorInvalidException"
    }
   }
  </code></pre>
  
  <p>Has anyone else run into this problem or perhaps know what might be causing this? Like I said I was able to register two other achievements before this for the same app.</p>
