I was playing on Easy and when the Scrin arrived, I purposely kept the MCV from reaching anywhere near the docks so I could kill all the Scrin invading units. After a while after the Tripods were coming, they had a Mothership coming towards my MCV. I tried finding this on various gameguides but none of them mentioned anything about a Mothership being deployed. Was this random or some sort of glitch?
