I know, I know. Necropost. But I am experiencing the exact same issue in Oct '21. Construction Yard is destroyed, the first mission following the Highliner, game freezes. I don't believe it is the Victory condition, as I have saved the CY for last, destroyed it first, and captured with engineer, anything. I have also attempted across all three Houses. Have any of you uncovered a workaround or even what's causing the issue in the first place? Could it have anything to do with the Tleilaxu/Ix alliance? This is the first mission where you can work with them in any way.
