I put in a ticket for this but it is now very consistent. At a certain point in my games since 1.7, I am no longer getting Ideology events upon colonization of a planet.
I sent in a ticket, screen shots and a save game.
I am just wondering if anyone else has had this problem. This is not a 'one time' bug (for me). This is the third game this has had this happen. I simply stop getting events and also choices to get Ideology points.
