Sorry I'm still crashing here in M6 (same place in mission as pre-patch) when I restart the mission after failing the first attempt at it.
At least exiting the game and starting it again appears to allow me to play past the crash point, just any proceeding attempts without exiting from the game first brings back the crash. Unfortunately I keep dying or losing the Theseus before I can complete the mission at the moment but I'm usually getting past the part after the
Theseus loses it's FTL drive and then begins restoring it
I'll try using old collisions again and try to run off a debug log.
