<p>Hello Simon,<o:p></o:p></p>
<p>I had a quick look into this today, and spoke a bit with Ben about it. We don't have a clear answer as to what is causing this at the moment. We'll have to look more into this early next week.
<o:p></o:p></p>
<p>> It means I can’t validate at all.<o:p></o:p></p>
<p>So you've tried to validate multiple times? I.e. does the error happen deterministically or was it more of a one off event?<o:p></o:p></p>
