Oh Kathy, what a shame. that is just the pits, I hate when you do a whole lot of work turn it over and its just a mess, happened to me too. Perhaps if you turn it off and then start it again it will sort it. I find that helps mine. Other than that a clean, no part of the needle in there is there.
That mare is another I believe, she was acting strange so they put her in there, at least thats what I think happened. I am not very good and telling horses apart.
