I am not sure if this is related to this update but there is now the option to include terrain in blueprinting.
Is there no permission we can do to prohibit having players bringing and copying terrain into the server? It genuinely defeats our type of economy at present.
You can prevent the placement of blueprints. Im not sure how but it is done on most servers for exactly the reason you mention. Some even prohibit the crafting of the blueprints completely.
