Either using own mining ships, or using any combination of the ones inside this BP: {F6790} (Place inside blueprints to access)
1) Spawn ships and set up the fleet in any combination or number
2) Go to a sector containing at least 1 asteroid, Tell fleet to "Mine This Sector"
3) Notice the AI react and move, but fail to ever begin mining operations in almost all cases. They will tend to sit in one place, unmoving. Note that there is odd behaviour with their salvage beams when there is any mining.
