>Heinrix dialogue about killing that Magus in first Genestealer combat encounter from act II triggered only now, in late act IV when I already dealt with all of them including their Patriarch and their cells on that random planet and Dargonus
Why are those dialogues set to trigger so absurdly rarely anyway? There is a ton of voiced companion banter in game and during playthrough you won't even hear a fraction of it because it almost never triggers just because
A separate issue is them only consisting of one character saying something and then second guy responding without actual back and forth exchange. Which is again weirdly nonsensical design.
