I know there have been a lot of questions around the "Another Gate Opened" mission back in the days and almost always the solution was that someone missed a zone.
But... I have all three Cartographer Achievements for Torride, Cold Star, and Home of Light, proving that I have discovered all zones. But I already had them before the mission started.
So is it possible, that this is one of the last few bugs that never got fixed, or is the winning condition actually different from discovering all zones?
