Drawing template occasionally blank when creating multiple drawings

I am using the API to automatically generate a bunch of drawings. The user is prompted to select a drawing template, and then the drawings are created in a loop. For some reason, there are always a few drawings in the set which don't load the selected template. I suspect it has something to do with creating new documents so quickly, but what should I do to address this?

I'm using SolidWorks 2012 SP 2.0.

I have provided excerpts from my code below (C#) to show what I'm doing.

<p>//...</p><p></p><p>string drawingTemplate = SelectDrawingTemplate();</p><p></p><p>if (string.IsNullOrWhiteSpace(drawingTemplate))</p><p>    return;</p><p></p><p>var bodyFeatures = GetBodyFeatures(partDocument);</p><p></p><p>foreach (IBody2 bodyFeature in bodyFeatures)</p><p>{</p><p>    //...</p><p>    var drawing = NewDrawing(drawingTemplate);</p><p>    //...</p><p>}</p><p></p><p>//...</p>

The NewDrawing method looks like this:

<p>private IDrawingDoc NewDrawing(string drawingTemplate)</p><p>{</p><p>    if (!File.Exists(drawingTemplate))</p><p>        throw new Exception("Drawing template does not exist.");</p><p></p><p><span style="font-family: 'Lucida Grande', Arial, Helvetica, sans-serif; background-color: #ffffff;">    int paperSizeA = (int)swDwgPaperSizes_e.swDwgPaperAsize;</span></p><p></p><p>    return (IDrawingDoc)SolidWorks.Application.NewDocument(drawingTemplate, paperSizeA, 0, 0);</p><p>}</p>
