Custom post type – update_meta not working

OK, this was actually a problem with another plugin.

When using more than one Custom Post Type and the save_post action, a wp_nonce should be used to verify which plugin the action is actually coming from.

Without this, all of my CPTs were trying to fire this CPT’s save_post action which consequently broke all of them. D’oh!
