[Q]

You will see this only on colonies with breatheble athmosphere, because usually the facilities with system wide abilities are built after the fifth or sixth facility. This means you see it usually only after the AI uses athmosphere converters and usually with the system robotoid, system computer complex and system intel facilities, because they are built on the three main colony types. The system gravitational shield e.g. is mainly built on military colonies and these are mostly limited to one colony per system! But all depends on the colony type and facility contruction files of the AI.
