Don't know if this has already come up, but I've had this bug to occur. A page can become "corrupted" if the publish button is pressed if the editor is loading. The only way to fix the page is to edit and save a previous state. Might want to consider having the preview and publish buttons disabled during loading if this can't be fixed.

Other than what I've mentioned above, the only small issue I have with the new editor is that the preview window does not allow you to test links and some things like collapsible tables and tabber don't function in the window, making it difficult to tell if something is working properly on page until it has been saved.
