The site was doing great and was moving up the serps and its PR was increasing. I wasn't really adding content to it and one day I decided to add a page and I submitted a site map to Google. The next day my site was gone and now it shows up on page 22 with quotes ... before it was on page 1 with no quotes. I've checked google webmasters tool and no errors and the site is still PR 3 (not greyed out or anything).
Is this just one of those Google dances. Please help
