Fixed on your site. Your Island articles were corrupt (they had no version history), which was making it impossible for VaultWiki to update the missing data. Islands that were modified after the corruption were able to be re-attached by the script. Unfortunately it's probably impossible to tell when the corruption occurred or what caused it at this point, so if there was an uncorrected flaw in recent versions of VaultWiki, it will likely remain for the time being. Either way, fixed the missing attachments on your site.
