Any ideas what to do to fix this? I have daily backups and can revert but a coworker did do a lot of work yesterday (not on these reports) that would get lost if I did so.

Take a gateway backup of the current state before you revert, so you can cherry pick the modified resources.

Error on line 1 implies the resources got stomped somehow. So, yes.
