I've been trying to force a modded civ to start out homeless, like the Terrans do in the Tutorial, but I'm having no luck. I tried makinga galactic event to force the homeworld to be removed as the game starts:
But nothing happens. I think the most likely problem is that there is no indication of which planet the event should remove, but I couldn't find a way to indicate that. Strangely, the only other event where DestroyObject is used (remove a Starbase in someone else's territory), the system seems to know which starbase it is about automatically.
PS. Please don't suggest giving my custom race the "DeadSystem" homeworld, I know it exists, but it doesn't fit my idea.
