There's nothing outside the scope. You probably had grandfathered plots if you had more than 1 FC plot location. New rules were implemented to make it so that you can only have 1 FC plot and 1 personal house for your entire (account) on any world server. Now if the FCs are owned by others, they can likely bid to move the plot. But you personally are limited to 1 FC and one personal plot owned.

This is direct from the dev's play guide itself:
In wards designated first come, first served, an available plot of land can be immediately purchased by accessing the placard at its entrance. See purchase requirements.
* Players may only purchase one private and one free company plot per World on any given service account.
