I'm encountering a very strange problem with a custom post type I've set up. Sometimes, but not always, when a new post is created or another edited, one post in particular loses all meta data. Just that one post. And it's not all the time, it seems to be almost random. I can't for the life of me think of what could be causing it, and I'm hoping someone else has seen this issue before and can point me in the right direction.
