I think this is probably relevant to the issue. I have audited my page since the last update as it seemed to slow right down – and I am getting a 404 error – for none.png for selecting no pattern.
I have tried selecting a pattern (pattern 7 it seems!) and I get the following 404, and there is no pattern; – so it seems it is looking in the wrong place.
