Damn, bad news! That smuggler mission seemed promising with sneak&seize beginning!
I think the source of troubles remain a mistery then as it's the launcher what crash. Whole game need to restart - albeit strange that on the different maps such things always happen in a given time interval. But it seems some troubles trully tide to AI. When the player has a larger base with more units such crashes are rarer.
Oh!
The very last mission of the War of the Landsraad, where everyone vs Bene Tleilax... The Ordos version... Is it intentional that noone attacks their base? No ground forces, no airstrikes? Playing as Harkonnen or Atreides my bases were at least bombed. Not to mention the stealth raiders what essentially insta-win for Ordos! You just gather 10-15 and hunt down the tleilaxu CYs and Repair pads then just let the other forces finish the job!
