I had a knot like that a couple weeks ago on a spool of gutterman. I was quilting on my frame, going a million miles an hour. I just happened to stop and see it. It would have been ugly if I hadn't chanced to see it.
No I didn't contact the company, didn't think of it until later when the evidence was gone.
