have you noticed, that the government information on the galaxy map is bugged?
Lidar is showen as "feudal" but it is actual "patronage". Ekondhri is shown as "corporate" but is actual "feudal". Chiutl is showen as "patronage" but it is actual a "cooperative".
I have raised a Bug-report some time ago about this problem and they "are looking into this". But i have NO idea how this affects the fortification Trigger or if it even affects it. Because i have no idea nor anyone else that i have asked, i have decided to do at the moment nothing in terms of flipping systems to CCC to be on the safe site. We simply don't know exactly which one reduces the trigger, what is showen on galaxy map or what is real government.
But if AA's really would care about this and would have taken a look at this, they would have noticed
And nobody should forget, that missions affext also the eceiving factions since some time. If you support one CCC faction in systems A with missions, it can happen that you support other factions in the systems B, C, D and E at the same time

Better keep a look WHICH missions you accept and which ones you decline. We have found missions to support a faction with personal weapons, but we were at war with them. Great Job from FDevs but you need to look out for such things.
