We have a Limit to how many Machines can be linked to a Production Line Control Station. Because of this, we should have a Master Control Station to Handel them.

When a Machine Group requires 7 Line Control Stations (that is at Maximum Level), you know you need something to keep it under Control. Especially for Mega-Lines.

Right now, I'm looking at a Control Group for Trousers... That needs 7 Computers to Handle...
