This shouldn't be a caching problem as this faction took control of the system several months ago. I agree that it is still independent.
The only possible problem it could induce is related to the insertion of PMFs. One of the criteria is that the new PMF has to be of the same allegiance as the system into which it is being inserted. The result of the test is going to depend on which data set the inserters refer to. It would be more than a little setback to discover that a carefully crafted PMF was rejected - after an eleven-month wait - because of a recurring bug.
sirius corporation yesterday showed as dictatorship in left hand corner of the hud, station and galaxy map, while still being corporate in right hand panel and system map. no idea how that glitch happens.
Is there a website where I can find out result of faction election without logging in to the game?
if the system is updated, eddb.io is your friend.
