Some of the homeworlds will incorrectly start with double factories and ships! In other words; 2 Frig factories, 2 CapShip factories, and 4 scouts & 4 constructors! What's especially unfair is: some teams will get the extras while others won't. Its gotta be a bug. I seriously doubt this was intentional.
(PS. Just start an Entrenchment game on the Double Cross medium sized map, with Quick Start enabled, and check to see what everyone gets at the start. Note, you can immediately Surrender, then choose Keep Playing to get a quick overview of what everyone owns),
