GetAsteroid(0):Die()
This causes asteroid ID 0 to go sort of black, but seeds can still be sent to it from neighbouring asteroids. Once they arrive, they get "stuck" and the player cannot move them.
Is this a bug..? The behaviour I was expecting was complete removal of the asteroid from the level, so that it cannot be seen (visually), or travelled to/from, by any empire, with any trees, flowers, seedlings, mines, sucked down along with it..
