Hello Brandon

Thanks for posting in the Lucid Community! 

Can you try opening the document in a Chrome Incognito browsing session? This often improves performance by starting a fresh cookie session and disabling your extensions. If you can see your work from the docs list but it’s gone once you open your document then check out this Community post (in English)! If you have access to the feature you can also check the revision history to see if the changes are there. Please see this article for information on how to restore from a previous version.

It is also worth noting that saving issues are often related to an unstable internet connection. You may want to look at your internet connection to confirm that this is not a factor. If you have not yet lost the work and your Lucidchart document continuously shows "saving" it is important that you do not close your document refresh your browser or restart your computer until your work is saved. To proceed with your work you can copy the content of your document to another Lucidchart document by following the steps in this article.

If the issue persists please reach out to support@lucidchart.com and we can help you get this resolved!
