I'm having trouble selecting units docked in the UEF experimental Atlantis aircraft carrier, (I presume the behaviour is similar for other carriers too).
You can build dozens of units in the thing, but in the selection bar each unit is displayed individually, (units of the same type are not stacked). Given the number of units the carrier can contain even with a full screen width selection bar the unit list goes several pages off the selection bar. The problem is that every time the selection bar is scrolled the current selection is lost, and every time a new unit is built the selection bar is rescrolled to the beginning.
The combination of these two behaviours makes it pretty much impossible to select what you want to launch.
Am I misunderstanding the behaviour or is there another way which enables you to select what you wish to deploy, or at least deploy all units of a specific type?
