Players see only active structures on their own worlds, but see the entire industry table for foreign worlds. E.g., the chronimium refinery structure is visible on all foreign worlds regardless of whether chronimium deposits exist. This could give players the wrong idea about how structures and deposits work.
The only structures on other players' world's that are of interest to a player are the structures that are manually built: defense, habitat and tech program structures. Everything else can be omitted when viewing a foreign world's structures tab.
