Hello!,
I figured out there are Class M modules in the games. These things are HUGE!
To enable to feature in the type set 00155F4A to 1 (exactly as written) in the console. To verify if it was enable type help ShipBuilderAllowLargeModules in the console. It should pop up under global variables as = 1.00 (optional)
Extremely experimental and can cause games to crash while building. I found this and currently playing with it more.
