So "Other Fallen-wizards may not use this site as a Wizardhaven [W]." does not prevent other Fallen-wizards from using their versions of the site as a Wizardhaven [W].
I propose the following erratum:
Playable during the site phase on a Border-hold site if you have 10 or more stage points. This site becomes one of your Wizardhavens [W] and loses all automatic-attacks. Nothing is considered playable as written on the site. If one of your companies is at this site, all attacks against it are canceled. Other Fallen-wizards may not use any versions of this site as a Wizardhaven [W]. Discard this card when the site is discarded or returned to its lacation deck. It cannot be discarded otherwise.
