well, there are a few ways i would go about getting around the foolish owner to fix it.
1. contact who ever 'owns' the land, as in whoever the region belongs to if possible. im not quite sure if thats a viable option, since most of the land i own are private islands that belong to one person or another.
2. if you have parcle access rights, remove them from the list of allowed groups, or set it to no access. if they complain, simply return the same reply they gave you. and ask them to configure the damn thing properly. if they do, remove the acess restrictions.
i dono, im just tossing ideas out there.
