title: "System.Numeric.Vectors" error when I send int with 4 digits
body: <p>I'm making a web service with ServiceStack, between its libraries he use System.Numeri.Vectors. I have a rare problem, the WS's request has a property int? (int nullable), everything works perfect until I send a value with 4 digits in said property (only with 4 digits run the error).</p>
  
  <p>Code:</p>
  
  <p>Request's definition</p>
  
  <pre><code>    [DataMember]
      public int? PaymentTypeId { get; set; }
  </code></pre>
  
  <p>Request in postman</p>
  
  <pre><code>"paymentTypeId": 2231
  </code></pre>
  
  <p>Error</p>
  
  <pre><code>"message": "No se puede cargar el archivo o ensamblado 'System.Numerics.Vectors, Version=4.1.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ni una de sus dependencias. El sistema no puede encontrar el archivo especificado."
  </code></pre>
  
  <p>PD: The error only happens if in paymentTypeId entered a 4-digit value, with 3 or 5 digits does not give error</p>
