I have a problem with attached sample file processing in Aspose.Words 15.4.0
It contains EQ field which is lost after saving document.
using (var inputStream = new FileStream(@"C:\test\test.docx", FileMode.Open))
using (var outputStream = new FileStream(@"C:\test\test_out.docx", FileMode.Create))
var doc = new Document(inputStream);
SaveFormat format = Aspose.Words.FileFormatUtil.LoadFormatToSaveFormat(doc.OriginalLoadFormat);
