Not a bug, not a feature either.

Empty sectors were not supposed to allow building any economy related stations,
but that was too harsh - and I did not have time to fully code player-side economies.

So:

Technically even empty sectors "have" economy type, and a list of allowed stations. That information is hidden on purpose.

Let's say that's a cheat or exploit or unfinished feature.


In case anyone is wondering, what's the intent behind station founding now:

- Economic stations are built inside faction sectors - your profit depends on population.

- Shipyards, and other non-economic stations are yours to build anywhere as hubs.
