Components Disappeared

I have a very large prototype and a smaller prototype all using the same components from an asset library. I had them both as cloud documents and saved them very consistently. Today I went to create a link for Maze.design using their XD plugin and after the plugin throwing an error, it removed many (not all) of the components. When I tried to go back to an older version, one of the documents says that the last save was done on November 23rd. I have been working on this file every day for a month and have had it saved. Any idea why the cloud versions wouldn't be there and why my components are gone?
