Our site was indexed and spidered a couple of months ago. I have since learned more about site content, design and optimizing for Google. I added and changed some of the content and created a more user friendly site. This month our main homepage was updated finally and cache refreshed on April 12th and then again on the 17th. It was the only updated page but it looked like my work had paid off and my search results vastly improved for that page. On the 19th I looked for our site and the updated page was now gone and only the old cached results from the previous design was left. The new page hasn't come back yet and I'm wondering if this is a worry or just a short wait?
