Released! Thanks guys!

Care to share?

Figured it out.
In my function, I was calling wp_update_post, which calls save_post.
Elsewhere, I had added an action to save_post which was overwriting the data.

More readable pastebin, without PHP syntax highlighting:

Forgot to add, using WP 3.4.2.

I can confirm that the problem is with revisions, as when I disable revisions (in wp-config), the code functions as desired.

Thanks for both responses – it was the cache. I had cleared the cache from within chrome but that must not have solved the problem.
