I would like to know, but it depends if I would fix it. I had this happen on a star block quilt I made. One of the points was reverse. I gave the quilt to a non quilter and let her know there was a mistake, but she had to find it. Well it has never been found, and she said that makes her quilt special and unique. It is like I said, it depends on what the quilt is going to or for what use.
