So, another interesting thing has just happened in Priva. Last night we had six factions: BCATS, Priva Industry, Priva Empire Group, Priva Partners, Values Party of Priva and Cartel of Priva. Cartel was on 1% influence. Tonight, Cartel has gone and a new faction has appeared - Cartu Empire League - with a state of Expansion (so they've come in-system from somewhere nearby). It would appear that not all systems can hold seven factions, and if a faction expands into an already full system then the lowest local faction is removed *or* if a faction expands into a nearby system and a local faction is at 1% influence then that faction is replaced.
Has anyone else seen this happen? From what little reading I've done on the BGS I get the impression the question of removing factions hadn't been answered yet.
