In the cancel star option what happen if we cancel a star with a planet gravitating having a population?
Example, I jump in a System which has a second star orbiting 30LY away and the system has generated an NPR on one of the planets there.
Did you test the above yet?
thanks
The intention of the star system design functionality is to build starting star systems for RP purposes, rather than for deleting parts of systems mid-campaign. I would not recommend the latter unless you are sure about what it is in the system. The "are you sure" popups before any deletion happens warn that affected populations will be deleted. However, the specific example above wouldn't be a problem because an NPR would not be generated in a location that cannot easily reach the primary star.
Even if an NPR or other population was on the system body, there are a lot of safeguards in place in C#. When a population is deleted, the following are also deleted; Research projects, queued research, sectors, admin commands, contacts for the pop/SY/ground forces, all fleet orders for fleets that had the pop as a destination, shipyards, shipyard tasks, commander assignments and ground forces. The NPR would still function in this scenario, even if you just deleted its capital, but it wouldn't be much of a threat.
BTW I assume you mean Delete. Cancel means you are NOT deleting or modifying the star.
