We just encountered a strange issue that was flagged by our client. It looks like a number of events--more than 5--disappeared. They longer appeared under the "Events -> Events" menu in the admin Dashboard, and were no longer visible on the frontend of the site.
We were able to recover the posts by importing them through an XML export from a previous Db backup, but this is a bit of a perplexing issue.
We'd like to know if there are any other cases were event posts disappeared from the admin/front end since this was an alarming issue for the client.
