Attribute disappeared

I added a listing attribute yesterday then added the attribute to a current listing. This morning, both the attribute on the listing and the attributes pages are gone. I am running a child theme and not aware of any updates last night. Any idea what could make this happen?

Please make sure that there are no other plugins or customizations that may cause this issue, e.g. this issue may occur if a website backup was restored automatically. HivePress itself doesn’t have any functions for deleting attributes, it only deletes listings automatically if you set the Storage Period in settings.

Thank you. I think something happened on my hosting provider end, actually. I have a ticket in.
