This has happened twice on both times I have played this campaign. I am playing on Steam.
First I tried not going the spy route to assassinate the order leaders, and went into a long game of 50+ minutes, when moving armies onto the middle road towards the headquarters, game crashes.
Second time I finished assassinating the order leaders, game crashes after I finished assassinating the order leaders and started moving my army onto the middle towards the headquarters. Restarted the save and went to assassinate the order leader again, then dropped a manual save. When starting to move my armies towards the middle towards headquarters, game crashes. Issue still occurs even when waiting out the time and not moving anything. I have both warning logs and session data txt, but can’t upload because I’m new here.
Game files have been verified, but redownloading will require too long for my connection to try at the moment.
